Tips for Scaling Recipes

Baking — Scaling baking recipes beyond 2× can affect texture. Consider splitting into separate batches.
Seasoning — When doubling, start with 1.5× the seasoning and taste-test. Spices don't scale linearly.
Cooking time — Larger volumes may need longer cook times. Use a thermometer to check doneness.
Pan size — If you scale up, use a larger pan to keep the same depth. Don't just overfill your current pan.
