Loosen
To loosen is to thin a thick sauce, purée or batter with a splash of liquid, or to free a cake from its pan. Here is what to add and how much at a time.
Also called Loosen the sauce, Thin out.
"Loosen" in a recipe usually means make something thick a little thinner and softer by stirring in a small amount of liquid. You loosen a pasta sauce with pasta water, a stiff dip with lemon juice, or a set purée with stock. Recipes also use it when you lighten a heavy mix before folding, and when you free a cake or tart from the sides of its pan.
How to do it
To loosen a sauce or purée:
- Pick a liquid that fits the dish: salted pasta water for pasta, stock for gravy and mash, milk for cheese sauce, water or lemon juice for hummus and tahini sauce.
- Add 1 to 2 tablespoons at a time.
- Stir or whisk well, and wait a moment before judging.
- Stop when it flows the way you want.
To loosen a batter before folding, stir in about a quarter of the whipped cream or egg whites roughly first, then fold in the rest gently.
To loosen a cake, run a thin knife around the inside edge of the pan, pressing against the pan, not the cake. Then turn it out onto a wire rack.
How to tell it is done
A loosened sauce coats food and moves easily in the pan without being watery. A loosened dip spreads smoothly and holds a soft swirl. Sauces thicken as they cool, so stop when it looks a bit looser than you want on the plate.
Common mistakes
- Pouring in a lot of liquid at once. It is easy to go too far, and then you have to reduce it again.
- Using plain water when a flavorful liquid is at hand. Water dilutes the taste.
- Loosening a sauce for pasta before the pasta goes in. Starch from the pasta thickens it again. Add the pasta, toss, then adjust.
- Forgetting to check the seasoning after adding salty stock or pasta water.
In recipes
"Loosen with a splash of pasta water" is very common in Italian recipes, which is why many say to reserve a cup before draining. "Loosen the mixture" before folding and "loosen the edges" of a cake are the other two uses. Leftover risotto, mashed potatoes and polenta all need loosening when reheated.
