Would it be alright to use ginger beer instead of ginger ale for Nigella's Chocolate Gingerbread?
Ginger beer and ginger ale are both fizzy non-alcoholic drinks. Ginger ale is made in the same way as most other carbonated drinks (sodas), with a ginger flavouring. Ginger beer is also fizzy but it is made with fresh ginger, sugar and yeast and is fermented to produce the bubbles. Ginger beer tends to be less sweet and have a slightly stronger spicy ginger flavour than ginger ale, though brands do vary. So you can certainly use ginger beer for the gingerbread icing, but just bear in mind that it has a slightly different flavour profile to ginger ale.
