Orange & Grand Marnier Ice Cream

Orange zest oleo-saccharum, crème anglaise, cold Grand Marnier finish

45 min (+ overnight) ~500 ml Intermediate

Orange & Grand Marnier base

  • 200 g heavy cream
  • 200 g whole milk
  • 85 g sugar
  • 2 oranges, zested
  • 40 g fresh orange juice
  • 3 egg yolks
  • 1 pinch salt
  • 25–35 g Grand Marnier

This is a crème anglaise ice cream built around orange in two layers: the zest is extracted first as an oleo-saccharum with the sugar, then the fresh juice and Grand Marnier are added only once the custard is cold. The result should be creamy, deeply orange, and finish with a warm, elegant liqueur note.

Method

Oleo-saccharum

  1. Combine the sugar and orange zest in a bowl.
  2. Rub together with your fingers until the sugar is moist, fragrant, and orange-tinted.
  3. Leave to rest 30–60 minutes so the sugar pulls the essential oils from the zest.

Infusion

  1. Add the milk and cream to the orange sugar.
  2. Heat gently until steaming, but do not boil.
  3. Remove from heat and infuse 15–20 minutes.

Crème anglaise

  1. Whisk the egg yolks with the salt.
  2. Temper the yolks by slowly pouring in the warm orange dairy while whisking.
  3. Return everything to the pan and cook gently to about 82°C, stirring constantly, until nappant.

Chill fast

  1. Strain if needed, then cool the custard quickly over an ice bath.
  2. Refrigerate until fully cold.

Add cold ingredients

  1. Once the base is cold, stir in the fresh orange juice.
  2. Add the Grand Marnier, starting with 25 g and going up to 35 g for a stronger finish.

Do not cook the juice or the alcohol; both go in cold to preserve freshness and avoid flattening the flavour.

Maturation and churning

  1. Rest in the fridge for at least 4 hours, ideally overnight.
  2. Churn in the ice cream maker until thick and creamy.
  3. Transfer to a container, cover directly on the surface, and freeze until scoopable.

Background

Oleo-saccharum is the key flavour step. Rubbing the zest into the sugar extracts orange oils more efficiently than simply steeping zest in hot dairy, giving the ice cream a rounder and deeper orange aroma.

Fresh orange juice is acidic and Grand Marnier contains alcohol, so both are added cold after the custard is cooked. Heating either one dulls the orange and drives off the liqueur's volatile aromatics.

Mistakes I've Made

  • Cooking the juice or alcohol. The orange tastes flat and the liqueur note disappears. Add both only once the base is cold.
  • Too much Grand Marnier. Above about 35 g, the texture becomes too soft because the alcohol inhibits freezing.
  • Boiling the custard. The yolks scramble and the base turns grainy. Cook gently to about 82°C and stop as soon as it coats the spoon.
  • Skipping maturation. The texture churns coarser and icier. Four hours is the minimum; overnight is better.
