China Moon Serrano-Lemongrass Vinegar

Infused vinegars are a quiet kitchen secret, and this one from Barbara Tropp’s China Moon Cookbook punches well above its four ingredients. You simmer rice vinegar with fresh ginger, bruised lemongrass and a handful of serrano chiles, then let it cool and steep into a bright, spicy, citrusy splash.

The method couldn’t be simpler, but two details matter. Use a non-aluminum pot, because acidic vinegar reacts with aluminum and picks up a metallic taste. And when you strain out the solids, resist the urge to press on them. Squeezing pushes out cloudy, bitter compounds and muddies an otherwise clear vinegar.

What you end up with is a versatile flavor bomb. A spoonful wakes up salad dressings, dipping sauces and marinades, and it’s a natural finishing splash for stir-fries, noodle bowls and steamed fish.

It keeps for weeks in a clean glass jar, growing more mellow and aromatic the longer it sits.

Pro Tips

• Bruise or smash the lemongrass and slice the ginger before simmering so they release more of their oils into the vinegar.
• Leave the serrano chiles whole for gentle warmth, or split them open for noticeably more heat.
• Always store it in glass, never metal, so the acid doesn’t react with the container.

Variations

• Add a strip of lime zest or a couple of kaffir lime leaves for an extra citrus note.
• Swap the serranos for milder jalapenos or fiery Thai bird chiles to dial the heat up or down.
