What is lotus root
Lotus root is an edible stem part of lotus plants. It is called ‘Renkon’ in Japanese, which you may have seen on bags of lotus root chips at the store.
It has a crunchy, starchy texture with a mild sweetness, and is often used in Asian cuisine as stews, stir-fries or even in salads.
With its unique appearance with lots of holes, it works well as a garnishing ingredient as well.

Tips
1. When baking 2 sheets at the same time, watch closely from around the 10 minute mark. Different racks in the oven bake differently so one of the sheets could start browning quicker than the other. You can also work in batches.
2. Adjust the baking time depending on the thickness of the slices. Thinner the crispier and quicker to cook.
