Using bloomed chocolate

Bloom is cosmetic. Melting removes it entirely, which makes bloomed chocolate perfectly good for anything that gets melted.

beginner

Bloomed chocolate has lost gloss, snap and some surface texture. It has not spoiled, is not mouldy and is not unsafe.

Melting redistributes fat bloom completely, so a bloomed bar in a ganache, a bake, a sauce or a hot chocolate is indistinguishable from a fresh one. Re-tempering restores a bloomed bar to a usable coating chocolate as well.

The one thing it should not be used for is anything where the surface will be seen without further processing — and that is an aesthetic limit rather than a quality one.

What it is for
To use chocolate that has bloomed rather than discarding it.
Working temperature
4050°C

Method

  1. 1. Check it is bloom rather than mould — bloom is grey or white and even; mould is fuzzy and coloured.

  2. 2. Use directly in anything melted: bake, ganache, sauce, hot chocolate.

  3. 3. For coating work, remelt fully and re-temper, which removes fat bloom entirely.
