"The first time I made this for my friends, they actually fell silent, the marinade is that good! While you might think tomato ketchup is strange to have in a marinade, it's actually a secret ingredient in some Chinese dishes. Perfect to use as a thickener, for sweetness and additional flavour layers. Use this recipe as a base and adapt to your own taste / what you have in your pantry! REFER TO THE NOTES for substitutions for most of the ingredients. MINIMUM MARINADE TIME: 1 hour (or overnight)..."
