Notes
I have use this 3 ingredient killer vegan burger sauce on my burger.You may add a slice of cheese if desired .You can bake the patties instead of frying on a skillet.I have made aloo tikki's that are 3.5 inches wide and 1 " tall .You can easily increase or decrease the recipe as per your requirement .Make ahead of time and freezing options mentioned above.Use zucchini instead of carrots and it's still delicious.Instead of flax meal slurry you can use cornflour plus all purpose flour slurry.Use store bought or homemade dry roasted bread crumbs for amazing crunch .Skip sesame seeds if unavailable.Use spices according to your spice level.These burgers are 4 on 5 spice level. 5 being hottest.Use herbs of your choice, mint goes well instead of cilantro.Add 1-2 teaspoon cornflour if the mixture doesn't bind.If catering to a large crowd , assemble the burger bread and tikkis warm in the oven at 200 deg F / 100 deg C for 1 hour. Assemble veggies and sauce just before serving .
