I tend to use sharwood light soy sauce ( 6.6 carb per 100ml)
so 25 ml is about 1.65 carb
and about 10ml of fish sauce ( 14carb per 100ml ) so 1.4 carbs
1/4 teaspoon chinese 5 spice ( listed as 5 carbs per tablespoon on my fitness pal) so 1/4 teaspoon is about 0.25 carb
1 clove chopped garlic ( 16.3 carb per 100 gram) so approx 0.8 of a carb
1 teaspoon cornflour ( 88 carb per 100gram ) so 1 teaspoon Approx 5 grams 4.4 gram carb
and an ounce or so of cold water to dissolve the corn flour before adding to the other ingredients
this all gets poured in to the stir fry wok about 1 minute from the end to glaze everything
total carbs for this sauce 8.8 carbs -- so divided per serving for 2 works out at
4.4 carbs per serving
really tasty too
