INGREDIENTS
6-8stalkslemongrassapprox. 1 cup when thinly sliced
12clovesgarlic
1wholeshallot
2wholeserrano peppers(slice the chili to remove some seeds, if you don't want too much heat)
¼cupgalangal rootor ¼ cup of chopped reg ginger plus 1 tablespoon of lime/lemon juice
1teaspoonturmeric powder
½teaspoonsalt
¼cuplime zest
METHOD
Peel and discard the tough outer leaves, root ends, and dry green tops of the lemongrass. Thinly slice the tender, pale yellow and light green inner core.
Carefully peel the skin of the galangal root using a small pairing knife or vegetable peeler.Zero-waste tip: Store the extras in the freezer and use when needed.
Use a zester to remove the outer layer of the limes. Make sure not to go deep into the white pith. Zero-waste tip: Squeeze out the lime juice and store it in an air-tight mason. Keep in the refrigerator and use as needed.
Roughly chop shallots, Serrano peppers, and peeled galangal root.Note: For a milder flavor, remove the seeds from the Serrano peppers.
Add all ingredients into the bowl of your food processor . Pulse 5-7 times to break up the fibrous lemongrass and tough galangal before switching to continuous blending.
Blend continuously until a thick, finely processed paste forms. Pause and scrape down the sides of the bowl as needed. If the mixture stops moving, add a splash of water just to free the blades.
Transfer the paste to an airtight glass jar or container. Let it rest at room temperature for 30 minutes to allow the aromatic oils to meld before using.
NOTES
Use the tender stalks: Remove the tough outer layers and use only the pale yellow and light green portions of the lemongrass for the best texture.
Slice it thinly: Thinly slicing the lemongrass before processing helps break down the tough fibers and prevents a stringy paste.
Go easy on the water: If the mixture isn't moving through the blades, add just a small splash of water at a time to keep the paste thick and flavorful.
Don't over blend: The finished paste should be thick and finely processed with no large pieces remaining, but it doesn't need to be completely smooth.
