I have just been having a blog convo on here about BBQ sauce as my optimizing book says Tomato sauce is 1 syn per tblsp and BBQ sauce is 0.5 syn per tblsp. But someone has commented that both are 1 syn per tblsp.
The basic syn value is indeed ½ syn but branded products may well have different values, such as the Heinz one. Where possible it's always best to go for the value for a particular brand rather than a generic syn value.
