Rendering Fat (Tallow & Lard)

02What you'll need

• Raw fat trim (beef/sheep fat for tallow, pork fat for lard)
• A heavy-based pot or slow cooker
• A strainer or cheesecloth
• Clean jars for storage

03Method

• 1. Cut fat into small, even pieces to render more evenly and quickly.
• 2. Melt slowly over low heat (or in a slow cooker), stirring occasionally.
• 3. Continue until solid bits (cracklings) separate from the clear liquid fat.
• 4. Strain through cheesecloth into clean jars while still liquid.
• 5. Cool completely, then store in a cool, dark place or refrigerate/freeze for longer storage.

04Troubleshooting

• Fat browns or smells burnt — heat was too high; always render low and slow, never rushed.
• Rendered fat has an off smell after storage — inadequate straining left impurities behind, shortening shelf life; strain thoroughly through fine cloth.
• Low yield — some fat trim yields more than others; leaf fat (internal) typically renders cleaner and more abundantly than back fat.
• Solidified fat has a grainy texture — usually cosmetic rather than a problem, though very slow cooling can sometimes produce a smoother set.
