Principles of Vegetable Cookery • Goal is to retain color, flavor, nutrient, and texture of vegetable • Cellulose structure softens, and they become less crisp • Starch absorbs water, swells, and become more soluble • Water-soluble vitamins from vegetables seep out into the cooking liquid - B and C vitamins and minerals
Amount of water • Loss of nutrients is reduced when cooked in small amount of water • Pan is covered to prevents both scorching and loss of water due to evaporation
Length of Cooking Time • Vitamins are destroyed by heat and overcooking • Cook only until fork tender and still slightly crisp • Overcooking dulls the bright colors of vegetables, lose their texture and shape and become mushy • Properly cooked vegetables retain their color, flavor, and texture and nutrients
Methods of Vegetable Cookery • Boil - boil small amount of water, add vegetables, return to boil, cover pan, reduce heat to a simmer • Baked - Wash thoroughly and place on oven rack • Panned - Stir-fry, braise (fat, low heat) • Steam - Water in bottom of pan, basket to hold food, cook over boiling water • Fried - pan, deep fry, batter/crumbs • Pressure cook - quick, good flavor, color • Broil - tomato, eggplant • Microwave - retain color, flavor, texture, and nutrients
Selection and Buying Vegetables • Canned - more water, cooked at processing time, graded by government • Fresh - more nutritious, crisp, firm, color, • Frozen - label information is your guide • Dried - beans, peas, legumes - Soak before cooking
Care and Storage of Vegetables • Refrigerate most vegetables. • Examinevegetables first before putting away. • Wash vegetables only if produce is dirty. • Tubers and root vegetables - store in a cool, dry, dark place. • Canned vegetables – store on shelf at room temperature, use within a year. • Frozen- use frozen vegetables immediately when thawed.
