There's definitely going to be a learning curve with this whole drying malarkey. Need to cut smaller bits next time (was trying not to cut too small in case the bits shrivelled up to nothing). And should just switch it on a bit later and leave it running overnight rather than getting up in the middle of the night to check it a couple of times. Switched it off around half-five because I really needed a full two hours sleep before getting up for work and didn't thnk it needed that much more time. But it did need a bit more. So, although some bits are a bit squishy rather than dried I'm happy with the results. I didn't actually try any until I got home from work this evening but the strawberry bits taste just like jam. Fabulous.
I just popped the finished product into a couple of glass jars and have them in the fridge. Will need to use them fairly quickly I think as they aren't all fully dried. Mind you, I don't think the strawberries would last long anyway.
650g of strawberries gave me 100g dried
425g onions gave me 50g dried
