When the best swap works
- Muffins and quick breads where the swap replaces 50% or less of the oil — banana puree at 1:1 keeps the crumb tender and the rise honest.
- Spiced batters like carrot cake or zucchini bread, where pumpkin puree's 1:1 ratio disappears into cinnamon and clove without telegraphing pumpkin.
- Vegan brownies and dense bar cookies, where moisture and binding matter more than lift and the 90% water content reads as fudgy rather than sodden.
