Ingredients
300g| ⅔ pound unripenedgreen tomato
1medium lemongrass stalk (about 1.5 oz | 45g)
1small clove garlic,lightly crushed
Generous ¼ teaspoon dried red pepper flakesor 1 fresh Thai or serrano chile, split lengthwise
Pinchof ground turmeric(optional)
¼plus ⅛ teaspoon fine sea salt
50g| ¼ cup sugar
135ml| ½ cup plus 1 tablespoon distilled white vinegar,Heinz preferred
120ml| ½ cup water
Instructions
Cut the tomato: Depending on the size of the tomato, keep them whole, or halve or quarter them. Regardless, cut the tomato crosswise into pieces about ¼ inch thick. Pack the tomato into a 2- to 3-cup glass jar. Set aside.
Prep the lemongrass: Trim the lemongrass of rough outer layers. Cut it two 3- to 4-inch pieces, then smack them with the back of a heavy knife or a meat tenderizer to break the fibers and release flavor.
Make the brine and assemble: Put the lemongrass in a small saucepan. Add the garlic, red pepper flakes, turmeric, salt, sugar, vinegar, and water. Bring to a boil, take off the heat, and wait for the bubbling to subside. Pour over the tomato. Use a spoon or spatula to gently push the tomato, lemongrass, and chile down. Aim to submerge them in the brine.
Cool, age, and eat: Let cool completely, partially covered, at room temperature. Cap and refrigerate overnight before eating. Keep for up to a month.
