1. In case the marinade is too runny, add a spoonful of besan to the mixture.
2. You can also prepare with tofu, paneer or chicken.
3. If you are preparing potato tikka on a stove top, just toast the marinated potatoes and vegetables in a pan (spread little oil around the potatoes and vegetables for toasting). Then pack it on skewrs or tooth picks, show on direct flame for a few seconds and serve.
4. You can add some cherry tomatoes or normal tomatoes, carrots too along with other veggies. But remember tomato slices tends to let out water while baking so you can skip it if you want.
