This makes a lovely replacement for that brunch mimosa. If you're able, fresh squeezed orange juice gives you the best result, but any orange juice will work.
2 oz ginger beer
2 oz soda water
2 oz fresh squeezed orange juice
4-6 dashes The Bitter Housewife Cardamom Bitters
Gently pour all ingredients into a tall glass with ice, give a gentle stir, and garnish with a slice of orange.
