Drain and rinse your can of chickpeas, then add to a small pot and sprinkle baking soda evenly over top.
Add enough water to cover the chickpeas, then boil on medium high for approximately 15-20 minutes, until the chickpeas are losing their skins and are soft to the touch.
In the meantime, add finely chopped garlic to a high-speed blender with lemon juice and salt. Don't blend; let sit for 10 minutes for the flavors to fuse together.
After 10 minutes have elapsed, add your good-quality tahini to the blender. Note: if you would like to flavor the hummus with roasted garlic, roasted red peppers, or other aromatics, add them at this step.
Blend ingredients until smooth, adding about 1/4 cup water if needed to help encourage the blending process.
At this point, your chickpeas should be ready. Drain and rinse them in a colander under cold water before adding to your blender. Add 1-2 tsp ground cumin, and blend.
While the ingredients are blending, add in 1 tbsp olive oil. Keep blending until desired consistency is reached and your hummus is smooth.
