Matt is right about trying things. Best to have failures when it doesn’t really matter. I’ve had more than a few. You also need to have the stuff. An example I use are canning jars and lids. If you plan on preserving stuff from the garden, how do you plan on doing so? If canning, then you will need hundreds of jars to set aside any meaningful volume. And even more lids.
I also mucked up my 1st attempt making strawberry jam. The end result was a much too sweet syrup for which only a single use was found…..putting it on vanilla ice cream. Even then it was too sweet but my father-in-law didn’t mind it so I gave it all to him. I have rhubarb ready to harvest and having never done anything with it before I suppose I’ll try to make some kind of jam.
