The first step is to peel the plantains or raw banana. Grease your hand with oil if it turns sticky. Cut both the ends and then remove the green skin completely. Immediately soak the whole banana in plain water to prevent it from blackening and to keep it fresh.
When you are ready to slice, wipe each banana dry. They should be completely dry before you slice them. Then slice them to medium thickness.
Place these slices on a kitchen towel to absorb the excess water. Spread them out.
DO NOT put these slices back in the water.
Meanwhile, heat oil in a kadai. Here is how to check if the oil is hot. Add one or two raw banana slices in the oil. If they come up steadily on top, then the oil is ready.
Carefully slide the slices in medium hot oil and deep fry. Do not crowd them. Do not fry on low flame as then the banana chips will absorb too much oil.
Prepare a mixture of salt and water. Gradually pour a teaspoon of salt water in the oil as they fry. Once the color changes to brown and they turn crisp, take them out. Repeat this step every time you fry the banana slices. This is the best way to add salt to these homemade banana chips.
Once you have fried the whole batch of these vegan chips, add black pepper and mix lightly. Then wait for them to cool down at room temperature. Transfer to an airtight container. Store it at room temperature.
