100.00%
Brown sugar

Quantity

Scaling

Method

Add tomato, sugar, and vinegar.
Simmer uncovered for 35 min–45 min, stirring frequently, until thick but still spoonable.
Cool, then refrigerate for at least 12 h before serving.
Retain the recorded Malt or apple cider vinegar option; the alternative uses the same declared quantity, in place of the first material.

Tomato sweetness and water content will change the final reduction time. The chutney should balance sweetness, acidity, salt, and warm spice rather than taste like tomato jam.

Recorded alternatives (no separate variation-specific testing observations were supplied):

Smooth: Pulse briefly after cooling while retaining some texture.
Raisins: Add 60 g raisins for the final 20 min of cooking.

Phase Outputs Used

Phase Output	Use
Tempered onion spices	Use `tempered-onion-spices`. Use all.

FAILURE MODES

Jam-like sweetness	unbalanced reduction	check acidity and spice balance
Scorched spices	excessive dry heat	add tomato after recorded brief spice cooking
