Ingredients for molecular cocktails: choosing your first technique

A cocktail can change texture without losing its balance. Ingredient choice depends on the technique: clarifying juice, supporting a garnish and making a sphere are different processes, each with specific conditions.

The drink comes before the effect

Start with flavour, dilution, acidity and temperature. An interesting texture cannot fix an unbalanced drink. Test the effect on a small portion of the base and assess how it changes during service.

Alcohol can affect hydration, gel formation and freezing. Do not transfer doses from an alcohol-free recipe to a spirit without testing.

Four possible approaches

• For a thicker water-based preparation, consider small quantities of xanthan gum or a starch for use without heat, such as Ultratex.
• For clearer juice, investigate treatment with Pectinex and subsequent filtration.
• For a bite with a liquid centre, start with alginate and calcium lactate, choosing direct or reverse spherification.
• For a defined gelled garnish, design an agar agar base and check the texture after cooling.

An example to try

Reverse spherification of a mojito helps explain the relationship between base, bath and rinsing. For the theory, see the complete spherification guide. Make only the amount needed for service and follow the same storage requirements as the ingredients in the processed drink.
