Gather all the ingredients.
Hon-mirin is made by fermenting sweet rice and contains nothing else. Aji-mirin or seasoned mirin may include wheat. You can substitute mirin with (sake/dry sherry/Chinese rice wine) + sugar. Use this as guide: 1 Tbsp. mirin = 1 Tbsp. sake + 1 tsp. sugar.
Keep the eggplant uncut until you’re ready to deep fry because they will change the color as soon as you cut them. Since we’re deep frying today, we will not soak the cut eggplants in water to remove bitterness as you would normally do to prepare eggplants.
Whisk the tempura batter vigorously every time you are ready to dredge the ingredients in the tempura batter. The bubbly tempura batter will help achieve crispy, light tempura shell around the vegetables/shrimps. Plus, rice flour will separate from water and stay at the bottom if you don’t whisk the mixture.
Pick up tempura crumbs in the oil between batches. The burnt crumb will attach to your tempura if you don’t clean them up, and oil will get darker once the crumbs become burnt and it leaves a bad flavor in the oil.
