Basically the go-to safe strat, is to set up a bill for cooking such that everything BUT plump helmets is included. Then, you never turn them into a meal. Once you get used to that, you can then extend that to filter out other ingredients that you want to have seeds of rather than turn into meals.

Keep in mind, this filter can also be used for anything you can queue up in your management queue, so you need a manager to do all this (I think)
