Is green enchilada sauce the same as salsa verde?
They are close cousins. Salsa verde is often chunkier and meant for dipping. Green enchilada sauce is usually smoother and lightly cooked so it coats and bakes well. You can use salsa verde in a pinch, but it may be thinner or more acidic depending on the brand.
How do I make it thicker?
First, simmer it a few extra minutes uncovered, stirring occasionally, until it coats a spoon. If it still feels thin, keep reducing. Tomatillos thicken naturally as the sauce cooks down, so it usually just needs a little time and patience.
For next time, start with a little less broth and add more only if you need it. I skip flour or cornstarch here because tomatillos thicken naturally with blending and reduction.
How do I make it less tangy?
Add 1 to 2 teaspoons of honey or sugar, or a bit more sautéed onion. Also make sure the tomatillos are fully cooked. Raw tomatillo flavor can read extra sharp.
Can I make it without a blender?
You can, but it will be rustic. Chop everything very small, mash the cooked tomatillos, and whisk as it simmers. A blender gets you that classic smooth enchilada sauce texture.
Can I use an immersion blender?
Yes. Let the pot cool for a minute or two, then blend right in the pot until smooth. It is not always quite as silky as a high-speed blender, but it is close and way less fussy.
What is the best chile for heat?
Jalapeño is friendly and mild. Serrano is a clean, sharper heat. For a smoky twist, blend in a little roasted poblano.
