Condition the raw material
Meat and fat between −2 °C and 2 °C. Warm fat smears in the grinder and the chorizo ends up looking like paste, not grain.
Fresh
Grilling chorizo
Fresh product is the most underestimated and the one that loses the most batches. There is no fermentation or drying to correct mistakes: what leaves the grinder is what the customer eats.
Formulation per 100 kg of batter
| Component | Amount | Why it is there |
|---|---|---|
| Lean pork (shoulder) | 55 – 60 kg | Provides the protein that binds. Shoulder over leg: younger collagen and less dryness. |
| Jowl or back fat | 22 – 25 kg | Fat is flavour and juiciness. Below 20 % the chorizo comes out dry on the grill. |
| Flake ice | 8 – 12 kg | Lowers temperature during mixing and makes the batter workable. Ice, never water. |
| Common salt | 1.8 – 2.2 kg | Extracts myofibrillar protein and preserves. Under 1.6 % it will not bind; over 2.4 % it tastes salty. |
| Sweet paprika | 1.0 – 1.5 kg | Colour and flavour. Good paprika stains the fat orange, not brown. |
| Fresh or powdered garlic | 0.3 – 0.5 kg | Powder doses more accurately and adds no free water. |
| Oregano, cumin, pepper | 0.2 – 0.4 kg | To suit the market. Cumin rules in the Caribbean, oregano in the Southern Cone. |
| White wine or vinegar | 1 – 2 kg | Slightly lowers pH and lifts the paprika. Optional. |
Process
Step by step, with the temperatures.
Grind
8 mm plate for visible grain; 6 mm for a finer texture. Grind fat and meat separately if the fat is soft.
Mix
Meat + salt + spices first, until it tacks up; then the fat and the ice. The batter must not exceed 8 °C.
Rest
12 to 24 h at 2 – 4 °C. This is where colour sets and flavour integrates. Skipping it shows in the first bite.
Stuff
Natural hog casing 32 – 34 mm, or edible collagen. No air: every bubble is a rancidity point.
Portion and chill
Linked or twisted at 10 – 12 cm. Into the chiller at 0 – 2 °C until packing.
| Control point | Value |
|---|---|
| Yield | 97 – 99 % on batter |
| Maximum batter temperature | 8 °C |
| Shelf life chilled (0 – 4 °C) | 5 – 7 days in natural casing |
| Shelf life frozen (−18 °C) | 3 months with no sensory loss |
| Usual calibre | 32 – 34 mm |
Troubleshooting
What went wrong, and why.
Half the craft is reading the defect. These are the ones that keep coming back.
| What you see | What caused it |
|---|---|
| Dry and crumbly | Fat below 20 %, or batter that went past 12 °C and broke the fat emulsion. |
| Turns brown within 24 h | Oxidised paprika or exposure to light and oxygen. Vacuum pack or use modified atmosphere. |
| Will not bind, splits when fried | Not enough salt or too short a mix: the protein was never extracted. Mix until the batter sticks to the glove. |
| Bubbles under the casing | Stuffed with air. Slow the stuffer down and prick before resting. |
Frequently asked
What people ask before they start.
Does fresh chorizo need nitrite?
It does not need it to keep, because it is eaten within days and cooked. Many producers add it purely for colour. If you do add it, the product counts as cured and must be declared and dosed as such: see the nitrite dosage sheet.
Why ice and not water?
Ice gives up cold as it melts and offsets the heat generated by friction in the grinder and mixer. With water the batter temperature climbs and the fat starts to smear.
How much fat is too much?
Above 30 % the grill hands it back to you: the chorizo shrinks and floods the plate. The comfortable commercial window is 22 to 25 %.
