Even though I thoroughly enjoy a good grapefruit, I avoided grapefruit smoothies for a long time because I was afraid of them being too bitter. I recently decided to try making one for variety and it was actually quite good. For starters I recommend using either a small grapefruit or a half because it can still be pretty bitter.
¼ cup water
½ grapefruit (peeled & seeds removed)
1 orange (peeled & seeds removed)
1 carrot (scrubbed)
1 apple (cored)
3 Tbsp chia seeds
1 cup frozen strawberries
5 ice cubes
Makes ~32 oz, or 2 medium servings. I peeled the grapefruit the same way I do oranges and removed the visible seeds. Blend on high until smooth and enjoy.
I tried this with several grapefruit varieties and close relatives of grapefruit. I tried Ruby Red, oro blanco, cocktail grapefruit, and pomelo. Our favorites were the ruby red and oro blanco, although they were all good. Also, there can be quite a bit of variation within a single type, so picking a top quality fruit is probably more important than the variety.
Russ Parsons has a short section on grapefruits in How to Pick a Peach. He recommends choosing heavy fruits with smooth skins and avoiding fruits with a recessed stem end.
If you want to go deluxe, you could use a grapefruit knife to remove the fruit from the membrane in sections, as the membrane adds some bitterness. I did not remove the membranes for the smoothies, but when I eat grapefruit straight I do like to scoop the fruit out of the membranes. I don’t often go for task-specific kitchen tools, but I have a soft spot for the grapefruit knife.Finally, remember that compounds found in grapefruit interact with some drugs, so if you or someone you feed is taking anything, make sure you check.
Thank you Adam. ..I have been looking for a recipe with grapefruit in it. Having it now and it’s wonderful. I used half fresh strawberries and half frozen peaches because that is what I had.. very good! Keep the recipes coming!
