Lamb Injection is the competition-tested way the Butchers Axe crew get savoury, herby flavour and serious moisture all the way to the middle of a big cut. Dissolve it, inject it, and let it work while the rub handles the outside. It's how the comp cooks keep a lamb shoulder juicy through a long, slow ride.
Savoury and herb-driven — yeast extract and vegetable powders build a deep, roasted umami base, lifted by herbs and spice. It reads like a concentrated lamb stock with a herby edge, seasoning the meat from within rather than sitting on the surface.
A fine, savoury powder that dissolves cleanly into warm liquid for injecting. Store cool, dry and airtight, out of the sun.
Ingredients: Flavours (natural flavouring complexes, vegetable protein extract, maltodextrin, colour 150d, flavour, vegetable oil), Mineral Salts 451, 341, Salt, Sugar, Yeast Extract, Vegetable Powders, Food Acid 262, Herbs and Spices, Spice Extract, Vegetable Gum 415.
Dietary: No gluten-free claim is made; may contain soy, gluten, milk, sesame, peanuts and tree nuts — always check the physical label.

Every serious lamb shoulder needs flavour working from the inside as well as out. Inject it the night before so the moisture settles deep, then let the rub build the crust while it smokes low and slow. Season the outside with Four Monkeys Lamb Rub and finish the plate with a mop of Boomas Boomtang BBQ Sauce. Juicy right through the middle.
How do I use it? Dissolve a quarter cup in 300ml of liquid, inject 5–7kg of lamb along the grain, then rest cold for 4–6 hours before cooking.
Does it add heat? No — it's a savoury, herby flavour and moisture injection with no chilli.
Is it gluten free? No gluten-free claim is made, and it may contain soy, gluten, milk, sesame, peanuts and tree nuts — always check the physical label.
Where is it made? Made in Australia, in Melbourne.
