Preheat oven to 400 degrees Fahrenheit.
De-stem and wash beets, then pierce all over with a fork [note#1].
Bake whole for 30-50 minutes, turning turning 1-2 times until you can pierce them through the center with a fork.
Remove from the over and let them cool completely, then rub off skin with your fingers.
Rough chop 3 of the beets and finely diced the 4th if you want texture at the end. If not, rough chop all four to combine with your other ingredients.
Combine all ingredients (except the diced beet), starting with the smaller amounts of each (i.e. 3/4 cups aquafaba, 2 cloves garlic, etc.), in your blender and blend until smooth. Pause to scrape down the sides, tasting and adding more ingredients as needed until you get your preferred texture and flavor.
Serve with bread, on sandwiches, with veggies, or spoon into your mouth by itself,
Enjoy!
