White chocolate and raspberry ice cream
White chocolate emulsified cold and raspberry pulp added afterwards. The sweetness of one cut by the acidity of the other.
The raspberry is here to cut: white chocolate is sweet and rich with nothing to balance it, and a good load of sharp fruit is enough to keep it from cloying.

Chef's notes
- ·Chocolate melted at 50 °C and emulsified at 15 °C · raspberry cold, afterwards.
- ·Do not skip the cold ageing: it hydrates proteins and stabiliser and clearly improves the texture.
- ·The serving temperature depends on your recipe: if you formulate to a softer PAC than your freezer (say -11 °C with the chest at -18 °C), temper it for 5–10 min before serving; if the PAC matches your freezer, it can be eaten straight out.
- ·Why formulate at -11 and not at -18 °C: even though your freezer sits at -18 °C, formulating at -11 makes the ice cream tastes better — at -18 it is so cold that the taste buds barely pick up the flavour and the fat is slow to melt in the mouth. And keeps better: ice cream formulated at -11 and kept at -18 has less free water, suffers less from Ostwald ripening (ice crystals joining and growing) and keeps its creaminess longer.
- ·Keep your own notes: write down the POD and PAC that work best with your machine.
The texture
spot on
Creamy and dense from the cocoa butter, with a sharp edge arriving at the finish. The raspberry brings water and acidity, and it is precisely that acidity that stops the white chocolate from cloying.
All about this white chocolate and raspberry ice cream
Against plain white chocolate, this version lowers the couverture and makes room for raspberry pulp. The fat drops considerably and the ice cream comes out far lighter.
The milk powder rises instead to hold up the solids, and the added sugar remains small: barely any sucrose, because the couverture brings its own. Sweetness and serving temperature stay in band.
The order matters: first the chocolate emulsified at 15 °C and only then, with the mix already cold, the raspberry. Fruit acid on hot chocolate helps nothing at all.
The ingredients and what each does
Every ingredient has a technical job: cream brings fat and creaminess, milk powder raises the non-fat solids, the sugars set the sweetness and the freezing point, and the stabiliser controls crystal growth during storage.
Technique and controlling the numbers
Adjusting the POD (sweetening power) and the PAC (antifreezing power, given as a target temperature) lets you match sweetness and hardness to your taste and your machine. With the selectors in the side bar the formula recalculates itself and you will see how the amount of each ingredient changes.
Storage and common mistakes
Store at -18 °C in an airtight container and avoid freeze-thaw cycles. The commonest faults are not ageing it enough, too much sugar so it never freezes properly, and over-churning, which whips in too much air and wrecks the texture.
