Culinary Notes
The "Plump" (Rehydration): A raisin is essentially a grape in hibernation. To get the best out of it, especially for baking, you should wake it up. Soak them in hot tea, orange juice, or rum for 15 minutes before adding them to a batter. This prevents them from sucking the moisture out of your cake, keeping the crumb moist.
The Burn Risk: Raisins have a very high sugar content. If they are exposed on the surface of a scone or bun, they will turn into bitter, black charcoal in the oven. Always push them deep into the dough to protect them.
Flour Dusting: In a thin batter, raisins have a tendency to sink to the bottom. Tossing them in a tablespoon of flour before folding them in creates friction, helping them stay suspended throughout the cake.
Savoury Use: Don't limit them to dessert. Raisins are classic in "Agrodolce" (sour-sweet) sauces, paired with pine nuts and vinegar in Italian spinach dishes, or in a coronation chicken sauce.
