Quick Breads Quick Breads… Flour mixtures with a fast-acting leavening agent. Do not have as much sugar & flavoring as cake or other desserts. 3 Types of Quick Breads… Pour Batter Ratio of flour to liquid is 1:1 Examples: waffles, pancakes, popovers Uses: breakfast, brunch, snacks Drop Batter Ratio of flour to liquid is 2:1 Examples: muffins, biscuits, coffee cake, fruit breads Uses: breakfast, brunch, dinner, desserts Soft Dough Ratio of flour to liquid is 3:1 Examples: biscuits, doughnuts, scones, coffee cakes Uses: breakfast, brunch, dinner, dessert Quick Bread Ingredients… Flour All-purpose is the one most commonly used When mixed with liquid, flour produces gluten protein from 2 other proteins: gliadin & glutenin Cornmeal & whole wheat flour are also used Liquid Dissolves dry ingredients Adds flavor & causes browning (milk) Examples: Milk Buttermilk Dry/evaporated milk (reconstituted) Water Fruit Juice Other Ingredients… Eggs Fat Types Oil Vegetable Shortening Butter Margarine Lard (pork fat) Functions: Tenderness Flavor Browning/appearance Bind ingredients as they coagulate Color, texture, & nutrition Salt for flavor Sugar Browning Flavor Color Brown sugar Molasses Leavening Agents 4 Types of leavening agents in quick breads Baking soda Baking powder Steam Air (carbon dioxide) Leavening Agents Cont. Chemical leavening agents An acid-base chemical reaction produces bubbles Double-acting & Fast-acting Bubbles start to form in the mixing bowl Slow-acting Bubbles form with the addition of heat (oven) Baking Powder Baking soda + an acid (cream of tartar) + cornstarch Steam and air leaven popovers & cream puffs Nutrition… Quick Breads have… Carbohydrates (starch & sugar) Vitamins (TRIN)-Flour is enriched with these Thiamin Riboflavin Iron Niacin Fruit Fiber (whole grain muffins) Principles of Quick Bread Preparation… 2 main principles 1. Gluten formation Liquid + flour = gluten Gluten forms mesh-like structure surrounding leavening gasses Gas expands gluten stretches Oven heat coagulates & sets the gluten protein 2. Activation of leavening agent Chemical reaction of leavening agent Methods of Preparation… Muffin Method Mix & sift dry ingredients Mix/beat together liquid, eggs, fat/oil Pour liquid into “well” in dry ingredients Mix only enough to dampen dry ingredients Do not overmix Biscuit Method Mix/sift dry ingredients “Cut-in” solid fat Pastry blender Crumble with fingers Grate in frozen butter Add liquid & toss and stir with a fork Knead for a short time Roll, cut, & bake Characteristics of Muffins… High Quality Muffins Thin, evenly-browned crust Top is symmetrical, but it looks rough Texture inside is uniform Crumb is tender and light Poor Quality Muffins Overmixing Overproduced gluten = tough bread Peaked top Pale with a slick crust Tunnels are visible inside muffin Undermixing = low volume, flat top Characteristics of Biscuits… High Quality Biscuits Even shape with a smooth & level top Straight sides & an evenly browned crust The interior is white to creamy-white Crumb is moist & fluffy and peels off in layers Poor Quality Biscuits Overmixing Low volume and a rounded top Top is smooth Crumb is tough and compact Undermixing Low volume Rounded top with a slightly rough crust Tender crumb Storage… 1-2 days at room temperature Freeze well Use a moisture-proof wrap
