Place peeled garlic into food processor or high powered blender i.e Vitamix/Nutri Bullet. Grind to a paste.
Add the red chili powder, cumin powder, salt and, sesame seeds. Blitz in the blender/processor until all of the ingredients are blended together.
COOKING THE MIXTURE IS OPTIONAL. I prefer to cook the mix to get rid of the raw garlic taste and preserve it a bit better. Add 2-3 tbsp oil (vegetable is what I used) to a pan and heat over medium-low. Transfer the blended ingredients to the pan and stir making sure to not burn the garlic. Add in the lime juice and keep stirring. If the garlic is starting to burn make sure you lower the heat.
Cook this mixture for about 5-7 minutes. Once the mixture has cooked, set aside and let it cool. Once cool, place in an airtight jar, layer the top of the lasanyu marchu with some oil and store in the fridge for up to 6 months. * See Recipe Notes
