January and February bring peak citrus, perfect for ovens that warm the kitchen and flavors that wake up winter palates. Lean into lemon, orange, grapefruit, and lime for tarts, pound cakes, and glazes that balance richness with sharp, fragrant zest. Fold zest into batters, finish warm cakes with citrus syrup, and stock curd or marmalade for quick desserts. Pair citrus with olive oil, almond meal, yogurt, and poppy seed for moist crumb and aroma. For best results, use room‑temperature eggs and butter, strain curds silky smooth, and garnish with candied peel for sparkle.
