Rehydrate soy curls in hot boiling water and cover with a lid for 10-15 minutes. Once soy curl have softened, drain the liquids with the strainer. Allow it to cool down for 5 minutes. Press out all the excess liquids of the soy curls. This will give the soy curls a better consistency when pan frying.
On a separate mixing bowl, whisk all marinade ingredients together. Drop in the soy curls and massage (or mix) thoroughly until all curls are fully coated. Cover and set aside in the fridge for 30 minutes - 1 hour to marinate. If you have less time, 15 minutes minimum will do.
Preheat a cast iron skillet or sauté pan to medium high heat. Remove soy curls out of the fridge. Toss the soy curls into the pan and stir until brown. You will know soy curls are ready when it has slightly dried up. Pour a tablespoon of Filipino dark vinegar and mix to finish (this is optional, it's really for the dark "beef" color of tapa).
