Ahhhhhhhhhhhhhh. I finally understand why the vegetables I cooked went from raw to over-cooked like that [insert finger-snapping here]. This week was focused on the proper preparation of vegatables. C'mon, I know everyone has ordered green beans at a restaurant and said to themselves, "I can do that. It's beans and oil." I also know that when you try it at home, you get one of these results:
1. Army green/khaki colored, mushy green beans
2. Brightly colored and undercooked burnt beans
I don't care if you do or do not understand food science but it's really helping me, so I'm gonna write about it and it explains how and WHY everyone gets those same results at home.
Lots of vegetables get boiled right? Of course; but nobody knows how long. Wanna know
why? .......
Each vegetable has a very different structural integrity; from species to species and size to size, each vegetable is different.
Rule #1: Cut all your vegetables into uniform sizes and shapes so that each piece cooks evenly. This addresses the problem with weird shapes: make them all the same relative size and they will cook at the same speed (among the same type of veggie).
Rule #2: Cook as short as possible to preserve texture, color and nutrients. Most vegetables get overcooked!
Rule #3: When cooking different vegetables in a medley, cook them separately. Cook them in order of starch content and add less starchy vegetables after more starchy ones.
Now, here is the big science piece that helps me understand this best. All vegetables have at least some level of cellulose, which is an undigestable fiber that makes up the cell walls of vegetables. Cooking vegetables breaks down that cellulose. Some vegetables need to break down more or less than others. My favorite examples are zucchini and beets. Zucchini can be sliced and eaten raw (doesn't need to be broken down); beets on the other hand, need to be cooked to have a desireable taste (needs to break down lots of cellulose). Basically, if you'd eat it raw, it needs less cooking than those that you wouldn't. This week in class we applied that common sense and put it to action. This is the main factor in vegetables.
Know your food.
Know which take longer to cook.
Other than vegetable science, this week, we learned and applied several different cooking methods to vegetables in order to display their versatility. There are 3 types of cooking methods:
1. Dry-heat method
2. Moist-heat method
3. Combination method.
To kill 2 birds with one stone, we learned both vegetable preparation and cooking methods.
On Monday, we prepared:
Grilled Vegetables
- Grilling is a dry-heat cooking method.
- Rule #1 is the most important when grilling. We marinated onions, zucchini and mushrooms. Each of these have different cellulose contents, but with grilled foods, you'd expect different textures but uniform heat and char. Size is the most important issue becuase if one item is thicker than the rest, the other don't get the same heat and/or grill contact as the thinner items.

don't get the same heat and/or grill contact as the thinner items. When grilling, you should be aware of the cellulose content of the items grilled together. Grilling is best for higher heat, lower cellulose veggies. Can you imagine grilling a potato or beet? You'd need to pre-cook something with that much starch. To get the appropriate look, uniformity of shape is imporant, because when you lay skewers down on the grill, you want all of the veggies to get good grill marks. If they are improperly cut, some veggies touch the grill, other end up suspended.
Sauteed Green Beans:
Finally, we are back to my original example. Sauteeing is a dry-heat cooking method. The way to avoid bad beans is to understand that the integrity of this vegetable requires a little bit of breakdown before it can be enjoyed. Raw beans taste chewy and bitter. To counteract this, they

should be par-boiled (par-boiled = blanching + extra time) to break down the cellulose. The beans are then shocked in a cold water bath to stop the cooking. If not shocked, the hot beans will continue cooking themselves and make themselves mushy (mushy = bad, for the most part). Just before service, you add the cooled, par-boiled beans to a heated, buttered pan and saute until hot. Minimal cooking retains more nutrients and maintains color.
Roasted Acorn Squash:
- Roasted = Baked. They are both a dry-heat cooking method.

- This was the least exciting food to prepare on Monday. Cut in half; cook; flip; season (the only fun part: butter,brown sugar and orange juice); cook more. The service was cool though; it came in it's own bowls!
Braised Lettuce: - Braising is a Combination cooking method. - Wilting greens is not new. Very common cooked wilted greens are spinach, mustard and collard greens. I had not ever heard of wilted Romaine until this week. Apparently, Europe does not see Romaine as a cold salad lettuce the same way as we do in the U.S. For this dish, we blanched the lettuce in already boiling water (blanching = add vegetable to boiling water and remove when water returns to a simmer). After the water returns to a simmer, we removed the lettuce from the heat and shocked it in ice water. Boring, so far, right? Then, I halved the head without cutting it in half... basically unfolded it. With the unfolded lettuce, I broke the stems in thirds and folded it into itself (fold the bottom third up and the top third over the bottom third) to create a long rectangle. I quartered this rectangle into 4 servings. These then went into a pan, topped with mirepoix, and finished in the oven. Suprisingly awesome. Dude, it's cooked lettuce and it really tastes good. -- Mom, I'll make this at a family event and people will think it's gourmet.... it's braised lettuce!--

Broccoli Hollandaise:
- Par-boiled Broccoli is a moist-heat method.
- Again, par-boiling = blanching + more time. Par-boiling is used on tougher vegetables. The general rule is that if it grows below ground (root veggies, etc.), you should par-boil it. We all know that broccoli is more tender cooked but can get a little flavor-less all by itself. Here, we added Hollandaise sauce (yes, we applied our previous learning to make Hollandaise) to the broccoli. mmmmmmmmmmmmm.... much better.
Tempura Vegetables:
- Frying is a dry-heat cooking method. Yes, you heard right. This is because dry-heat = direct contact. In this case, the frying oil becomes the heating element. The heating element is in direct contact with the cooking food, therefore it is a dry-heat method.

- To prepare tempura batter, Stormy mixed egg yolks, sifted flour and cold water. She skewered her veggies and dipped them in flour and then the batter (the flour removes moisture which helps the egg-yolk-based batter adhere to the veggies) and placed them in the deep fryer. For battered items, you want employ the "swimming method", where the cooking items just float in the hot oil, so that they don't stick to the fry-basket while cooking.
On Tuesday, we prepared:
Glazed Batonnets of Carrots:

- Sauteing is a dry-heat method
- Batonnet = 1/4" x 1/4" x 2" cuts
- This preparation is a fairly easy glaze. Chicken stock + butter + sugar added in a saute pan to the carrots. When the liquid reduces to a syrupy texture, you're done. Very simple, very tasty and sweet.
Glazed Beets:
- Another glaze, another dry-heat method saute.
- Not a lot of people in class were beet fans. I am. I took charge of the beet preparation. I couldn't wait. And......then I screwed up twice. I broke my glaze 2 times. Glaze is a reduction of the cooking liquid. In this case, butter, lemon juice, sugar and beet juice. The first time, I had too much fat to reduce and when the liquid (lemon juice) evaporated, the sauce broke. To fix it, I should have added more liquid. I made the mistake of adding more butter; it was melted, so I figured melted = liquid. However, butter = fat. And fat is a dry cooking method. Ooops. Chef Pierre had me pull out the beets and tried to restart the glaze with water (Water = liquid). Unsuccessful. He had me toss this glaze and restart it. This time, I used less fat to get the glaze started. The glaze was working well the 2nd time when I added back the beets. By the 2nd application to the saute pan, the beets were near done so I didn't cook the 2nd glaze long enough. Upon service, the beets were well cooked (slightly colored) and sweet enough (I used the sugar twice), but did not have the thick glaze coating it because the 2nd glaze didn't have enough time to reduce. Lesson learned; be patient and do it right the first time.

I think the funny story of the week had to be beet-related though. To start the beets, we needed to par-boil them and peel them. After they become tender, we shocked them in cold water and then I started peeling. In case you didn't know, beets bleed. That red, blood-stains everything. I wore gloves when I peeled them and had plastic wrap on the cutting board that I was peeling onto. On one of the corners however, an air pocket had developed and while peeling my gloved thumb pressed the air pocket and it burst like a pimple. Gross!! Drops of purple juice shot in every direction, including directly back at me. My chef's coat got drilled with staining blood. And unlike blood, this doesn't come out with cold water. During a break, I worked it over with the Tide-Pen that I keep in my car, thinking I was a genious for having one. It turned a purple dots into a huge pink target!!! Here I am 2-days later after overnight soaks in Oxy-Clean and it's finally white again. Lesson learned... don't mess with beet juice.
Ratatouille:
- It's a glamour stew. Stewing is also a combination cooking method.
- Of course, the first thing you think of is the Disney-Pixar movie. And just like the cooks in the

Gusteau kitchen, ratatouille is viewed as a dish for the commoner.
However, when done well and not over-cooked, it can be a tender summer favorite. Now, to be traditional, our vegetables were a large dice (3/4" cubes) to reflect the rustic origins, not the "fussed-up, fancy, thin-sliced" disney preparation. This is a dish that I will keep on had though. It is an amazing conglomerate of vegetables caught directly between undercooked and mushy... really hard to describe beyond that and the word "Awesome".
Summer Squash Stir-Fry:
- Stir-fry foods are prepared in a wok on high heat. This is fast-frying or fast-saute and is a dry-heat method.
- For this dish, we cut the veggies (leeks, zucchini and yellow squash) into long julienne. Long Julienne = 3" x 1/16th" x 1/16th" = painstaking. The point is to make the veggies look like noodles. I'm just going to let you know (without the in-class emotion) that these cuts take FOREVER to do properly! This preparation is a good example of rule #3. Zucchini and Yellow Squash cook much faster than leeks. The leeks need to be added first and when the start to get tender, we added the faster cooking summer squashes.

We stir-fried these in oil and basically served them garnish-less. For the most part, I went into class understanding that wok cooking = high heat + constant movement. However, Stormy, having grown up in Hawaii, gave me a little extra insight. I had the heat on Medium-High and knew that they needed to keep moving in the pan; Stormy says, "high-er heat and move it faster. Don't let it sit". She also added extra oil, appropriately using sesame oil, adding an extra flavor component that many of the other teams didn't have.
Cauliflower "Au Gratin":
- Au Gratin basically means topped and browned. Most often with cheese and bechamel and broiled in the oven.

- The whole cauliflower is par-boiled until tender and cooled. Before service, it is covered with bechamel sauce (yes, we made that before too) and parmesan cheese and broiled in the oven until the sauce and cheese start to brown.
--Aside: I haven't mentioned it yet because there is no magic time for tenderness on vegetables. Al Dente doneness is determined when you spear the toughest spot of the vegetables with a paring knife. If it pulls out without sticking, you're done. If it sticks, it needs more cooking. If it destroys the structure, you've over-cooked it unless you plan on pureeing it.--
They are grinding it in me, I'll pass it on to you.
Science + Technique = good cooking
