What each ingredient does

Flax seed
Releases soluble gum into the water as it steeps, giving the drink body and a slightly thick texture.
Lemon juice
Adds acidity that brightens the flavour and balances the sweetness.
Loaf sugar
Adds sweetness, adjusted to taste.

The step that matters

Thinning with more water if too thick. Flax seed gum thickens the liquid the longer it steeps and once lemon is added. Adding water as needed keeps the lemonade pourable and stops the body from becoming gluey.
