Light Corn Syrup
good1:1
The closest structural swap for American kitchens — same anti-crystallising role, much blander. Add a little brown sugar or honey for flavour.
Both are invert-style syrups that block sucrose crystallisation; corn syrup simply carries none of golden syrup's caramel notes.
Honey
good1:1 by weight
Nearly identical density (21 g per tablespoon on both labels). Adds floral flavour and browns faster — lower the oven 10°C for delicate bakes.
Honey is a natural invert syrup with similar water content, but its fructose share makes it brown more aggressively.
Maple Syrup
moderate1:1 by volume, reduce other liquid slightly
Thinner and less sweet; changes flavour completely. A rescue, not a match.
Maple is mostly sucrose in water rather than invert sugar, so it protects less against crystallising and adds more moisture.
