ha! you're not so strange - our garage fridge has a big 3-4litre bucket of fish food in it (DH buys it in bulk and it's the safest place to store it). I've never actually bought buttermilk and a lot of the 'regular ingredients' that seem to be in every pinterest recipe, we don't have but i know all these food discussions in the past have led you to know that about Aust. We have a lot of Asian food ingredients in the fridge (condiments that sit there like forever and drive me nuts b/c they take up space!) Aloe/Green Tea after sun gel and eye drops are the only other real non-food things in the inside fridge - and apart from fish food, the fermented gross stinky Bokashi (japanese compost) bucket we used more frequently before FOGO (Food Organics, Garden Organics ) became a thing in our area and DH's fishing bait stuff
