Trim off the stem ends of the eggplants. Roll-cut them into about 1.5-inch wedges: hold your knife at a 45-degree angle, make one cut, then roll the eggplant a quarter turn and cut again. Repeat until all the eggplant is cut.
In a large bowl, combine the water and vinegar. Add the eggplant and place a small plate on top to keep the pieces submerged. Soak for 15 minutes.
Drain well and pat the eggplant dry. Transfer to a large mixing bowl, sprinkle with starch, and toss until the pieces are lightly coated on all sides.
Prep the tofu, aromatics, and sauce
Cut the tofu puffs into triangles or 1-inch pieces, if needed.
Finely mince the garlic and ginger. Set them aside with the dried chili peppers.
In a small bowl, stir together all the garlic basil sauce ingredients. Stir again right before adding it to the pan because the starch will settle at the bottom.
Pan-fry the eggplant
Preheat a large non-stick sauté pan over medium-low heat until it feels hot. Add 1.5 tablespoons of oil.
Increase the heat to medium-high. Add the eggplant in a single layer and pan-fry for 2 minutes on the first side.
Flip the eggplant, add the remaining 1 tablespoon oil, and pan-fry for 2 more minutes, or until the centers begin to soften and the outside looks lightly crisp.
Finish the dish
Add the garlic, ginger, chili peppers, and salt. Sauté for about 30 seconds, until fragrant.
Add the tofu puffs and stir the sauce one more time before pouring it into the pan. Add the basil.
Turn the heat to high and toss for about 1 minute, until the sauce thickens and coats the eggplant and tofu.
Transfer to a large serving plate and serve warm with steamed rice.

Notes
Eggplant options: Italian eggplant or graffiti eggplant also works. Slice into 2.5 to 3-inch spears and add about 1 more minute per side when pan-frying.
Tofu puffs: Store-bought tofu puffs are usually found in the refrigerated aisle at Asian grocery stores. Homemade tofu puffs also work; air fry or shallow fry them until golden before adding.
Using regular tofu: Use medium-firm tofu or soft tofu, not silken tofu. It may break a little when tossed. Pat dry, season lightly with salt and garlic granules, coat with oil, then dust with starch. Pan-fry until crisp before combining with the eggplant.
Chili pepper substitutes: Use 1 whole Thai red chili pepper or 1 red Fresno pepper, sliced with the seeds removed.
Make-ahead: You can make the tofu puffs 1 day ahead. Let them cool completely, then store them in the fridge.
Storage and reheating: Store leftovers in an airtight container in the fridge for up to 4 days. Reheat in the microwave on medium for 1 minute, or until warmed through.
