render
REN-der
/ˈrɛndər/
To melt down fat from animal tissue by slow heating, clarifying it for cooking or preservation.
In butchery and cooking, this specifically means converting solid fat (like suet or pork fatback) into liquid fat (like tallow or lard) while separating out the solid connective tissue.
The story behind the word. Coming from the Vulgar Latin 'rendere' (to give back or yield), the word has many meanings in English. In the kitchen, it literally means to force the fatty tissue to 'yield' or 'give back' its liquid gold when subjected to heat.
Word relationships
- melt: Melt is a general term for changing any solid to liquid with heat, whereas render specifically means melting animal fat to separate it from connective tissue.
- clarify: Clarify means to remove impurities from a liquid (like butter), while render involves both melting the solid tissue and clarifying the resulting fat.
- solidify: Solidify is the process of a liquid turning back into a solid, which happens to rendered fat when it cools.
Commonly confused with
- render (artistic): Render can also mean to submit, translate, or depict artistically, which is homographic but contextually distinct from culinary fat rendering.

When not to use
