How much to add...

[furbs]

Ive just got in a 100ml bottle of banana bread from Yaeliq but im finding the flavor too weak, i have some banana and nut flavorings, i want quite a strong flavor, im just not sure how much to add?

Any wizards here help?

I'd start by tweaking a small bottle , no more than 5 or 10ml and keep a note of what you've done for a larger quantity . . . it'll end in tears if you try and do the whole 100ml at once, quite possibly.

Maybe 5% Banana & 1-2% Nut to start with . . . .

Cheers, good idea about the small bottle.
5% and 2% and go from there sounds good.
