Ooo... what kind of smoothies did you make?
Pretty much whatever I had around. My go-to for hot summer days is the following (there are no measurements because I do it by sight, just gauge the proportions as I see it. You can adjust how much of each to change the dominating flavor:
Frozen strawberries
Banana
Vanilla
Strawberry, raspberry, or blueberry yogurt
Orange juice
NO ICE - using frozen fruit and yogurt makes the overall consistency much smoother, and the flavor won't end up diluted by, essentially, water. Same concept of having ice cubes in your drink, and then your drink sucks and is too watery if you wait too long to drink it.
Making half the strawberry frozen mango instead does great things for the texture, and is considerably more tropical. You should have more frozen fruit than any other ingredient.
