How Tallow Is Made

How Tallow Is Made

From raw suet to clean, traditional tallow.

Tallow has been made for generations by slowly separating pure fat from moisture, connective tissue and impurities.

While modern commercial production often uses large-scale equipment, traditional rendering relies on time, patience and gentle heat to create a clean, versatile product suitable for a wide range of uses.

  • At Healing Season, we follow a traditional multi-stage rendering process designed to produce clean, hard tallow with very little scent and a long shelf life.

What Is Tallow?

Tallow is rendered beef fat.

The process of rendering removes moisture, proteins and impurities from raw fat, leaving behind a stable fat that can be used for:

  • Soap making

  • Skincare products

  • Balms

  • Household products

  • Traditional cooking

  • Candle making

  • The quality of the finished tallow depends largely on how carefully it is rendered and purified.

Step 1: Preparing the Suet

  • The process begins with raw beef suet.
  • Suet is the firm fat traditionally found around the kidneys and loins of cattle and has long been considered one of the best fats for producing quality tallow.
  • Before rendering begins, the suet is minced into very small pieces.
  • This step is important because connective tissue can trap pockets of fat, making it more difficult for the tallow to separate during rendering. By reducing the fat to a smaller, more consistent size, more of the tallow can be released efficiently and evenly.
  • For us, a mincer produces the ideal size for rendering and helps maximise the amount of clean tallow recovered from each batch.

Step 2: Gentle Steam Rendering

  • Rather than placing the fat directly into a slow cooker for the initial render, we use a steam-rendering process.
  • The minced suet is placed above a pot of hot salted water where gentle steam slowly melts the fat.
  • One of the reasons we prefer this method is that unwanted odours can develop when proteins and small particles in the fat begin cooking directly in the melted tallow. This can happen when raw fat is rendered entirely in a slow cooker from the beginning.
  • Using gentle steam allows the fat to separate gradually while helping keep temperatures controlled. The salt and water assist in drawing out impurities and moisture while beginning the purification process.
  • The result is a cleaner first render and a tallow with significantly less scent before it even reaches the slow cooker stage.

Step 3: Slow Cooker Purification

  • Once the fat has melted, it is transferred to a slow cooker.
  • The tallow is then held at a low temperature for several hours.
  • During this stage:

  • Remaining moisture continues to evaporate

  • Small particles separate

  • Heavier impurities settle

  • Lighter impurities rise

  • This slow process allows the fat to clarify naturally without exposing it to excessive heat.

Step 4: Straining Through Muslin Cloth

  • The rendered fat is carefully strained through muslin cloth.
  • This removes:

  • Small particles

  • Sediment

  • Remaining solids

  • The result is a cleaner and more refined tallow.

Step 5: Cooling and Cleaning

  • The strained tallow is poured into containers and left to cool and harden.
  • As the tallow sets:

  • The purified fat rises and solidifies

  • Residual water settles underneath

  • Remaining impurities collect at the bottom

  • Once fully set, the tallow is removed from the containers and any residue on the underside is carefully cleaned away.

Step 6: Repeated Rendering for Purity

  • The process doesn't stop after a single render.
  • To achieve a cleaner and more refined product, the tallow is returned to a clean slow cooker and gently melted again.
  • It is then:

  1. Rendered

  2. Strained

  3. Allowed to set

  • This process is repeated multiple times.
  • Each rendering cycle helps remove:

  • Additional moisture

  • Remaining sediment

  • Fine impurities

  • Compounds that can contribute to unwanted scent

  • The result is a firm, smooth tallow with very little scent.

Why Multiple Renders Matter

  • Many traditional rendering methods involve repeated purification.
  • While it takes longer, the benefits include:

  • Cleaner appearance

  • Harder finished tallow

  • Reduced odour

  • Improved consistency

  • Better performance in soaps and balms

  • Longer storage life

  • For skincare and soap making, a clean tallow makes a noticeable difference in the finished product.

Shelf Life

  • One of the keys to long-lasting tallow is moisture removal.
  • Water encourages spoilage.
  • Through repeated rendering and purification, most moisture is removed from the finished tallow.
  • When stored correctly in a cool, dry place, properly rendered tallow can remain stable for 12 months or longer.

Why We Take Our Time

  • Rendering tallow properly is not a fast process.
  • It requires patience, gentle heat and multiple stages of purification.
  • At Healing Season, we believe the extra time is worthwhile because it produces a cleaner, harder and more versatile tallow that performs beautifully in soaps, balms and traditional household products.
  • Sometimes the old ways really are worth preserving.
