Some things are better tinned, frozen etc. But I pretty much cook EVERYTHING from scratch.

Tinned tomatoes are better than most fresh tomatoes you can get year round in aus. Frozen veg are similar. Dried herbs have their place too.

I make my own spice mixes, curry pastes, etc. I even make my own taco mix. I have lots of jars in my cupboard with mixes already made up so I can grab it easily and use.

I don't use packet mixes. Or premixed sauces/jars etc.
