Tree Nut Free Herb Roux
A good roux is the quiet backbone of so many classic sauces, and this herb version elevates that humble base with the bright, earthy lift of fresh thyme and parsley. It comes together with just butter, flour, and a pinch of sea salt — nothing hidden, nothing complicated, and absolutely no tree nuts anywhere in sight. That matters more than you might think, since some specialty or flavored cooking bases can sneak in nut oils or nut-derived thickeners that make label-reading a chore. Here, every ingredient is straightforward and easy to verify. The technique is simple but deliberate: low heat, constant stirring, and patience until the paste turns a pale straw color and smells faintly toasty — that's your signal it's ready. From there, whisk in warm milk for a silky béchamel or swap in broth for a velouté, and you've got the foundation for a genuinely impressive sauce. Make a batch ahead and stash portions in the freezer so a restaurant-quality sauce is always just minutes away.

- ¼ tsp fine sea salt
- 1 tsp fresh thyme leaves (optional)

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.
