Pescatarian Herb Roux
Butter and flour cooked low and slow — it sounds almost too simple, but a well-made roux is the secret behind some of the most satisfying sauces in the kitchen. This version builds real depth by cooking the paste until it smells faintly nutty and turns a pale straw color, which takes the raw flour edge completely off. Fresh thyme folded in off the heat adds a subtle herbal lift that makes any sauce built on top of it taste genuinely homemade. Whether you're whisking in warm milk for a silky béchamel or using seafood broth for a velouté to spoon over fish or shellfish, this roux gives you a clean, reliable foundation every time. The parsley stirred in just before serving keeps things bright and fresh rather than heavy. It stores beautifully in the fridge or freezer, so making a batch ahead means a restaurant-quality sauce is never more than a few minutes away.

Melt the butter in a small heavy-bottomed saucepan over medium-low heat until fully melted and just beginning to foam, about 1 minute. Do not let it brown.

Add the flour all at once and stir immediately with a wooden spoon or silicone spatula, working the mixture into a smooth paste. Continue stirring constantly for 2–3 minutes, until the roux smells faintly nutty and turns a pale straw color — it should pull away from the sides of the pan slightly and look dry on the surface.
