How to make a proper cream liqueur at home

Using the actual industrial ingredients, scaled for a kitchen blender

The problem with most home recipes

Most recipes for homemade Baileys-style liqueurs use condensed milk, double cream thickened with sugar, or other workarounds. These produce something approximating the flavour but the emulsion is unstable — it separates on standing, has a short shelf life, and the texture is wrong.

The industrial process uses sodium caseinate as the emulsifier, sodium citrate as a stabiliser, and a high-pressure homogeniser. Home versions of this process are assumed to be inaccessible because the equipment is industrial. That assumption turns out to be wrong.

How it actually works

Sodium caseinate (a milk protein) coats fat droplets and prevents them from coalescing. Sodium citrate sequesters calcium ions that would otherwise cause the caseinate to aggregate and destabilise the emulsion. The alcohol content — typically 17% ABV in commercial products — acts as a preservative. A kitchen blender run for long enough provides sufficient shear to achieve homogenisation.

Ingredients

This recipe makes approximately 1 litre.

Ingredient Amount
Blended Scotch whisky (40% ABV) 500g (approximately 500ml)
Double cream 300ml
White sugar 200g
Sodium caseinate, food grade 30g
Sodium citrate, food grade (E331) 1g

Sodium caseinate must be food-grade — Bacarél is a reliable UK supplier. Fishing bait caseinate is not food-grade and should not be used. Sodium citrate (E331) is widely available from home-cooking suppliers and on eBay. Bells or Whyte & Mackay are inexpensive and work well as the base spirit.

Method

  1. Add all ingredients to a blender. Sprinkle the sodium caseinate onto the whisky first to reduce clumping, then add the cream and sugar.

  2. Blend on high speed for 10 minutes continuously.

    At around 2 to 3 minutes, the mixture will appear to curdle and separate. This is expected. Do not stop. Continue blending — the emulsion will recombine and stabilise.

    This is the stage where most attempts fail. What is happening is the same process as when cream is over-whipped and becomes butter: the fat globules coalesce under mechanical stress into larger clumps. Continued blending breaks those clumps back down to a size small enough for the caseinate to coat and stabilise each droplet, forming a permanent emulsion. Stopping at the curdling stage and discarding the batch is the single most common mistake.

  3. After 10 minutes the mixture should be smooth, stable, and uniform. The sugar will have dissolved fully. The mixture will be noticeably warm from the blending — this is normal and does not affect the final result.

  4. Bottle and refrigerate.

The industrial process runs at 50–65°C with a cooling and reheating step between homogenisation stages, confirming that warmth during processing is not detrimental. Source: patent IES65347B2.

Equipment

A 500w Kenwood blender produces a stable result. Any comparable kitchen blender should be sufficient — a Nutribullet or similar high-power machine will also work. There is no need for specialist equipment.

ABV and shelf life

500g whisky at 40% ABV = ~200ml pure alcohol
Total volume ≈ 925ml
ABV ≈ 200 ÷ 925 = ~21.6%

The finished liqueur is approximately 20% ABV, which is above the 17% ABV of commercial cream liqueurs. This is consistent with room-temperature shelf stability in commercial products, though refrigeration is recommended. Consumption within a few months is prudent for a home-produced product where microbial controls are less tightly managed than in industrial production.

This recipe produces a result comparable to commercial cream liqueurs using the same underlying chemistry, without condensed milk or other substitutes. The key finding is that a standard kitchen blender run for a full 10 minutes is sufficient for homogenisation — and that the apparent failure at the 2–3 minute mark is part of the process, not a sign that something has gone wrong.
