Blueberries are one of the few fruits with real research behind them for memory and thinking, and that is why I keep a bag of them in the freezer. Green apple keeps the glass drinkable rather than worthy, and mint stops it tasting flat. This is what I make on a morning when I have a lot of thinking to get through. It takes ten minutes and the colour alone is worth it.

2green applescored and quartered
10fresh mint leavesplus a sprig to serve
1/2lemonpeeled
Instructions
Juicer method
Rinse the blueberries and pick out any stalks. Core and quarter the apples, then peel the lemon and cut it in half.
Feed the apple through the juicer first, then the blueberries, then the mint and lemon. Berries are soft, so sandwiching them between the firmer apple keeps the pulp moving through the chute.
Stir the juice, then pour it into two glasses over ice. Drink it the same day.
Blender method
Put the blueberries, apple, mint and peeled lemon in a blender with 100ml cold water.
Blend on high for 45 seconds until there are no lumps left.
Pour it through a nut milk bag or a fine sieve into a jug, pressing the pulp with the back of a spoon to get the last of the juice out.
Serve over ice. If your apples are sharp, a teaspoon of honey takes the edge off.
Notes
Frozen blueberries work as well as fresh and are cheaper out of season. If you are using frozen, there is no need to thaw them first for the juicer, though the blender method is easier with them softened for a few minutes.Do not skip the lemon. Blueberries are low in acid, and without it the juice tastes muddy.It will separate as it sits. Give the glass a stir before you drink it.
