Add everything listed under vindaloo paste to a grinder or a blender- whole chilies, garlic, ginger, sugar, salt, pepper, mustard seeds, turmeric, vinegar, cloves and cinnamon.
Blend it till it's smooth. Add 1 teaspoon of water, if needed, to help make the paste.
Your Vindaloo curry paste is ready. You can refrigerate this for 2-3 weeks
Marinate the chicken in the curry paste for at least 15 minutes. It's best if you can do this for 12-24 hours.
Stove Top Cooking
Heat the 1 tablespoon oil in a pan on medium-high heat.
Once heated, add the onions.Cook till they are golden translucent whitish pink.
Add all the marinated chicken along with the marinade.
Add 1 cup of water to the bowl the chicken was marinated in. Get all the leftover marinade.
Add the water to the chicken in the pot. Give it a mix.
Cover and cook on low heat for 40-45 minutes. Open the curry and mix it a few times in the middle.
The curry is done when the chicken leg starts to tear up and the red oil floats on top.

Notes
Chicken - Ideally, On-the-bone chicken, cut into large pieces, is the best for this. You can also use chicken legs.
Serving
Vindaloo is traditionally served with sannas, which are fermented rice cakes that are like idlies. You can serve it with dinner rolls, bread, naan, and pav. Rice and rotis are also great serving options.I usually serve yogurt on the side. Especially while feeding people with low spice tolerance.
Chilies
Here is a handy little snippet on the heat of Vindaloo. Remember, lesser chili powder will mean less heat but it will also mean that the curry won't be bright red.Mild heat: 3-4 Kashmiri whole chili Moderate heat: 6-8 whole Kashmiri Chilies Very spicy heat: 10-12 whole Kashmiri Chilies. You can add sliced green chilies while sauteing if you want more than that.Tip: You can use ground Kashmiri chili powder if you do not have whole Red Kashmiri chilies. 1 tablespoon of Kashmiri Chili powder is roughly 5-6 Kashmiri red chilies.To decrease the spice level of the dish
Cut the chili and remove the seeds before using
Reduce the amount of chili used. This will change the color slightly, but the taste will still be on point.
Last resort for all curries- dilute the curry with coconut milk
To increase the spice Level
Add up to 15-18 chilies.
You can also supplement with green chilies or ground chili powder, but it will make the curry very, very spicy.
