Worcestershire Sauce

Combine all ingredients in a medium non-reactive saucepan (stainless steel or enamel — not aluminium). Bring to a full boil over medium-high heat, stirring to dissolve the molasses and break up the anchovy fillets. Once boiling, reduce heat to a bare simmer — just a few lazy bubbles breaking the surface. Simmer uncovered for 20 minutes, stirring occasionally, until the sauce has reduced by about 15% and smells deeply savory and spiced.

Remove the saucepan from the heat and allow the sauce to cool completely to room temperature — at least 60 minutes. Do not rush this with an ice bath; a rapid temperature change can drive off aromatic volatiles. While cooling, the sauce will thicken slightly as it approaches room temperature and any fat from the anchovies may form a thin skin on the surface.

Transfer the cooled sauce with all its whole spices and solids into a clean, wide-mouth glass jar. Cover with a piece of cheesecloth secured with a rubber band — you want air circulation, not a sealed lid, during fermentation. Store at cool room temperature (18-22°C), away from direct sunlight. Stir once daily with a clean spoon. Ferment for a minimum of 1 week, ideally 2 weeks — the flavors will knit together and mellow dramatically. The sauce will smell progressively less sharp and more complex.

Line a fine-mesh sieve with a double layer of damp cheesecloth and set it over a deep bowl. Pour the fermented sauce through in batches, pressing firmly on the solids with the back of a ladle to extract every drop of liquid. Discard the spent solids. The strained sauce should be smooth, completely clear of particulate, and deeply dark. Yield is approximately 200-220ml from this recipe.

Pour the strained sauce into a small saucepan and bring to a very gentle simmer. Reduce by 20-25% to concentrate the flavors and achieve the characteristic Worcester consistency — thin enough to shake from a bottle, thick enough to cling briefly to a spoon. This step is optional but highly recommended: it eliminates residual rawness from the fermentation and sets the final flavor. Cool completely before bottling. Refrigerated, keeps for 6 months.
