Your Halved Recipe
× 0.5Halving tips for your ingredients
Pan & time tip: use a pan roughly half the surface area of the original (e.g. 9×13 in → 8×8 in). Baking time usually stays close to the same or drops slightly — start checking a few minutes early.
Quick reference: halving tricky whole ingredients
1 eggWhisk it, then use ~2 tbsp (half) of the beaten egg. Save the rest for an omelet.
1 tsp baking powderUse ½ tsp exactly — it's precise enough to measure directly.
1 tsp baking sodaUse ½ tsp — don't round up, too much will taste metallic/soapy.
1 packet yeast (2¼ tsp)Use about 1 tsp; a slightly smaller amount is fine and dough will still rise.
1 garlic cloveUse about half a clove, minced — or one small clove if your cloves run small.
1 small onionUse about half by weight, or save the other half wrapped for your next dish.
