GRADE 9 Agriculture FOOD PRODUCTION PROCESSES – COOKING:USING FLOUR MIXTURES Notes
FOOD PRODUCTION PROCESSES — COOKING: USING FLOUR MIXTURES
Subject: Agriculture & Food Production • Subtopic: Using Flour Mixtures • Level: Age 14 (Kenya)
- Understand common local flours (unga) and why we mix them.
- Learn basic processes: measuring, sieving, mixing, kneading, cooking or baking.
- Make simple, nutritious recipes using mixed flours and record observations.
Common flours in Kenya (what you find in market)
- Wheat flour (unga ya ngano) — has gluten; makes dough stretchy (good for chapati, mandazi).
- Maize (corn) flour (unga ya mahindi) — used for ugali and uji; no gluten; coarse or fine types.
- Sorghum (mgai) and Millet (unga ya mtama) — nutritious, local; gluten-free; used in porridge, breads when mixed.
- Cassava flour (unga ya muhogo) — starchy, used in baking and ugali mixes.
- Rice or coconut flours — used for special snacks and cakes.
Why mix flours?
Mixing flours helps to:
- Improve nutrition — e.g., maize + millet adds more minerals and protein.
- Improve texture — wheat gives stretch and holds shape; blending with other flours can give crumbly or softer results.
- Lower cost — use some cheaper local flours with small amount of wheat for better results.
Basic terms (simple)
- Gluten: a protein in wheat that makes dough stretchy and traps air for rising.
- Sieve/sift: removing lumps and making flour light so mixes are smooth.
- Leavening: raising agents (baking powder or yeast) that make cakes or bread rise.
Simple process steps when using mixed flours
- Measure ingredients accurately (use cup or digital scale).
- Sift dry flours and leavening together to mix evenly.
- Mix wet ingredients (water, milk, eggs, oil) separately.
- Combine wet + dry gently — do not overmix (can make baked goods tough).
- Knead only for doughs needing gluten development (chapati, bread). Use less kneading if many non-gluten flours are present.
- Cook or bake according to recipe. Check for doneness with a skewer or touch test.
Practical tips for mixed flours
- If using little or no wheat, add an egg or extra liquid to bind the mixture.
- For bread-like texture, keep at least 60–70% wheat flour (for home trials).
- Start with small test batches (makes learning cheaper and safer).
- Label flours with date; store in airtight containers to avoid pests.
- Allergy note: wheat contains gluten — inform family members with allergies.
Simple recipes (student-friendly)
Hands-on time: 15–20 min • Makes ~6 small pancakes
Ingredients: 1 cup wheat flour, 1/2 cup maize flour, 1/4 cup millet or sorghum flour, 1 tbsp sugar, 1 tsp baking powder, a pinch salt, 1 egg (or mashed banana for vegans), 1 cup milk or water, 2 tbsp oil.
Method:
- Sift and mix dry flours + baking powder + salt + sugar.
- Whisk wet ingredients; pour into dry mix and stir until just combined.
- Heat pan with little oil, pour small ladle, cook until bubbles form then flip.
- Serve with fruit, honey, or stew.
Hands-on time: 10–15 min
Ingredients: 2 cups maize flour (unga ya mahindi), 1/2 cup millet or sorghum flour, 3 cups boiling water, pinch salt.
Method:
- Boil water in a pot. Add a little maize flour to make a paste, stir well.
- Gradually add rest of flour while stirring to avoid lumps.
- Cook on low heat and stir until firm. Shape and serve with sukuma wiki or stew.
Classroom experiment — Observe changes
Make three small doughs with same water but different mixes:
- A = 100% wheat flour
- B = 50% wheat + 50% maize
- C = 30% wheat + 35% millet + 35% maize
Knead each for 5 minutes. Observe feel (stretchy vs crumbly), rising (if using baking powder/yeast), and cooked texture. Note results in a table: texture, appearance, taste, ease of kneading.
Troubleshooting quick guide
- If dough is too dry — add water a tablespoon at a time.
- If batter is lumpy — sift flours; whisk better or use a sieve.
- If baked goods are dense — not enough gluten or too much heavy flour; add more wheat or a leavening agent.
- Burning on surface? Reduce heat and use a lid for even cooking.
- Wash hands before cooking and keep work surface clean.
- Use clean utensils and dry storage containers to avoid weevils.
- Be careful with hot pans and boiling water — ask an adult for help.
Tip for Kenyan students: Try using locally milled flours from the market (unga ya mtama, unga ya mtama) — they are nutritious and cheaper. Record which mixes your family prefers and why.
