To a medium-size pot, add canned chickpeas and a teaspoon of baking soda. Cover with water and bring to boil. Let it boil on medium heat for about 10 minutes until the chickpeas are soft. Then drain and rinse the chickpeas in cold water.
To a high-speed blender or a food processor, add the boiled chickpeas, lemon juice, tahini, olive oil, minced garlic clove, ground cumin, a pinch of sea salt, and ground pepper, and blend at high speed for about 30 seconds until smooth. While the blender is running, add about 4 tbsp of water (use tamper accelerator stick to make it easier to blend if using a high-speed blender).
Taste, and add more sea salt, lemon juice if necessary. Continue blending on high speed for about 1-2 more minutes until smooth and creamy. Add more water to loosen the hummus.
Scrape into a bowl, top with olive oil or any garnish of your choice, and serve with pita, as desired.
