How to balance a gelato recipe

A balanced gelato has the right amounts of fat, sugars, milk solids and water. Get them right and it’s smooth, not icy, and soft enough to scoop. Get them wrong and it’s icy, sandy, greasy or rock hard, whatever the flavour.

The target ranges

Each number is a share of the whole mix, by weight. These are the ranges gelato schools teach:

Sources differ a little: Callebaut gives fat 8–10% and total solids 39–43%. Pick one set and stick with it. “Sugars” here means the sugars you add: the lactose in milk is already counted in MSNF.

How to check a recipe

For each ingredient, multiply its weight by its share of each component, add them up, and divide by the total weight.

600 g whole milk at 3.5% fat gives 21 g of fat. 200 g cream at 35% gives 70 g. In a 1 kg mix, that’s 91 g: 9.1% fat, inside 6–12%.

Do the same for sugars, MSNF and total solids, then compare with the table.

What to change when a number is off

• Fat too low: swap some milk for cream. Too high: the other way round.
• MSNF too low: add a little skim milk powder. Milk alone rarely gets there.
• Too hard to scoop: swap some sugar for dextrose. It softens more without tasting sweeter (see PAC and POD).
• Too sweet: lower the sugar and raise the solids another way, with milk powder or a less sweet sugar.

Every change moves the other numbers too. Adding cream raises fat but also total solids, and dilutes everything else. That’s why balancing by hand takes a few rounds.

Or let a calculator do it

Scoopable does these rounds for you. Pick gelato, add your ingredients, and change any amount: it rebalances the rest so every number stays in range. To see a finished example, open the fior di latte recipe.
