Hi… I use a set of basic tins I got from Euro Cake Tins (i bought a set on ebay) which i like best. I also have pme and silverwood tins but I prefer the euro ones. I don’t like loose bottom tins or ones with rounded corners so I don’t have those. The oven I use is fan assisted electric (not industrial) , I’m very happy with it. I would recommend you user your own home oven until your business picks up – unless you can’t bake cakes properly in it. The same with the fridge/ freezer. Use what you have, just buy oven and fridge thermometers to make sure they work properly. Hope that helps.
