I've recently moved onto a narrowboat (for those from other countries you'll have to google as I think it's a peculiarly English thing, but it's a long thin boat with living accommodation) and unlike in the typical house I don't have a door between my kitchen and where the smoke alarm is (right outside the bedroom door - don't really want to put it the other side of that). The original smoke alarm was an ionisation type and pretty much any cooking, even just boiling the kettle set it off. I've replaced it with https://www.amazon.co.uk/gp/product/B013T9W2AE/ref=3Dox_sc_act_title_1?smid= =3DA2MTK2J2TB084L&psc=3D1 which is combined thermal and optical and no longer set off by my cooking, but then it's not supposed to be as what it should be detecting is something different. I presume yours is an ionisation type if your cooking is setting it off.
