Good news first: well-rendered tallow is one of the most forgiving fats in your kitchen. Because ours is rendered three times and strained through double cheesecloth, there is very little left in it that can spoil. A few simple habits keep it fresh to the last spoon.
Every tub carries a batch number and a best-before date: 12 months from the day it was packed. Unopened and kept somewhere cool and dark, it stays at its best for that whole time.
Tallow softens and can melt on a hot day or in a warm kitchen. That does not harm it at all: it sets again when it cools, though the texture may change slightly.
After frying chips or vetkoek, let the tallow cool until warm, then strain it through a fine sieve lined with cheesecloth or a coffee filter into a clean container. Keep it in the fridge and use it again two or three times for frying. It will darken a little each time, and it picks up flavours, so keep a separate container for fish.
Fresh tallow smells clean and mild, almost of nothing. If it smells sharp, sour, soapy or like old crayons, or shows any mould, throw it out. That is rare with clean tallow that has been stored well.
Running low? Our tubs go from 500 ml for the kitchen to 20 litre buckets for the serious fryer. Shop the range.
