If you love spicy food, you need to make this smoky Mexican chili paste!

Ever since I made my own, I never got back to store bought. It’s easy, completely customisable, and it adds a fantastic flavor boost to any dishes like this Keto Chili where you can use it instead of all of the spices. This chili paste is also great for marinating meat and adding a flavour to veggie sides such as cauliflower rice.

You can easily adjust the heat by using different chilies. I used 2 Chipotle, 4 Ancho, 2 Arbol, 2 Guajillo, 1 Passila, 1 Cascabel and 1 Mulato Chilies. This combination results in mild-spicy Mexican chili paste. If you prefer your chili paste mild, avoid using Chipotle peppers. If you prefer more heat, add some Arbol chilies or more Chipotle chilies.

It's best if you wear gloves when handling hot peppers, especially if you are sensitive. Make sure to wash your hands afterwards and avoid touching your eyes at any cost.

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.
