The extension doesn’t as such allow you to set prices on a multiply level (i.e different prices for different multiplications of the same ingredient – not at the moment anyway)

However, there’s a way you can work around this somewhat (which might or might not work in your particular scenario, don’t exactly know what you are trying to do)

you could have a custom group (cheese and bacon and ham for example) which a customer can select one of each only once (or permutations thereof) for 0.00.

you could now add a second ingredient (also called cheese ) for 0.50 which is not in this custom group, but just in a default group/setting

essentially now a customer can/should (depending on your settings of the custom group) choose 1x cheese for free from that aforementioned custom group.

if he wants to add another cheese, he has to add from the other/default group (at whatever price you set there….

hope that makes sense……(!?)
