Sofrito Cubano

Frying the paste until the oil splits 95 recipes

• It is being fried, not simmered: the paste is in fat over live heat and moving, holding a steady sizzle throughout rather than bubbling as a wet mass.
• The colour has deepened and darkened from raw to cooked, and the volume has visibly reduced and tightened.
• The split, the signal the whole technique is named for, is unmistakable when it comes: clear fat separates out and pools at the edges and on the surface, and the paste pulls away from the pan floor in one mass.
• The smell has turned from sharp and raw to round and fragrant, with no raw bite left from any of the aromatics that went into it.
• Nothing has caught: no black specks through the paste, no bitterness, and a pan floor that is browned but not burnt.

Where it goes wrong It was taken off as soon as it smelled good, before the fat separated; the raw edge of the aromatics is still in it, and the finished dish tastes thin and sharp no matter how long it simmers afterwards.

Mashing & puréeing 114 recipes

• Smooth to the degree the dish asks for, judged on the tongue rather than by eye: no lumps, no fibres, no grit, unless texture is the point.
• No gluey elasticity: a spoonful drops cleanly off the spoon rather than stretching in a rope behind it.
• The consistency holds: it mounds on a spoon and stays there, neither slumping flat nor standing so stiff that a spoon has to cut it.
• Nothing separates on the plate: no water or fat weeping out into a ring within a minute of serving.
• The colour is even throughout, with no streaks of unincorporated fat, liquid, or seasoning at the edges of the bowl.

Where it goes wrong A starchy ingredient met a high-speed blade, so the cells burst and released their starch: what should be light comes out as an elastic glue that lifts off the spoon in one mass.
