In Texas, I grew up drinking Root Beer Floats, but the Persian equivalent is bastani in fresh carrot juice.
If you’ve never juiced your own fresh, raw carrots, you may be surprised to find how sweet and delicious carrot juice is all on its own. I happen to have a juicer, but if you don’t have one on hand I’ve read that you can add your carrots with a little water to a blender, and then strain out the juice – easy!
If you prefer to buy your carrot juice from the grocery, be careful that it’s 100% carrot juice. Often carrot juice gets flavored with lemon, ginger, and other things that don’t go well with bastani.
