What lemon brings to a ginger blend

Lemon gives a ginger blend a clear, tart edge. A small squeeze can make a sweet mixture taste more defined; too much can leave the whole glass tasting sharply sour.

For a home mix, measure lemon by teaspoons at first. Stir after each addition and taste from a clean spoon. It is surprisingly easy to keep squeezing because the drink looks unchanged, then realize the citrus has taken over.

Lemon's role is different from orange's. Orange can form the broader fruit base, while lemon adjusts the edge. That is a useful way to think about a ginger-orange spritz: make the glass pleasant first, then decide whether it needs a little extra brightness. Lemon is optional in a recipe that already tastes balanced.
