To make Green Peas Appe, start by boiling 1 cup of green peas and then purée them, ensuring it's not too fine. Mix the pea purée with 1 cup of semolina, chopped ginger, optional green chillies, lemon juice or sour curd, baking soda, cumin powder, coriander powder, oil, and salt to taste. Add water to create a thick, flowy batter. Heat oil in a paniyaram pan, spoon the mixture into the cavities, cover, and cook for about 3 minutes. Flip and cook until golden.

Green Peas Appe are not gluten-free due to the use of semolina (suji), which is made from wheat. However, you can substitute semolina with gluten-free alternatives like chickpea flour or rice flour to make this dish suitable for a gluten-free diet.

If you don't have baking soda, you can use baking powder as a substitute in Green Peas Appe. Use about 1.5 teaspoons of baking powder instead of 1 teaspoon of baking soda. This will help the batter rise and create a light texture.

To store leftover Green Peas Appe, let them cool completely and then place them in an airtight container. They can be refrigerated for up to 2-3 days. To reheat, you can pan-fry them briefly or microwave them until heated through.

Green Peas Appe pair well with a variety of dips and side dishes. You can serve them with mint chutney, tamarind chutney, or yogurt for a refreshing contrast. Additionally, a side salad or pickles can complement the flavors nicely.
