Drying spring onions

Somehow I have managed to grow some mega spring onions over winter, they are HUGE and there's no way we can eat them all, so I thought I'd try drying them.  I just washed them, sliced thinly and spread them out in the drier. I often leave things overnight in the drier to air dry before I turn on the heat, this worked well with the onions too.  In the morning I turned on the drier, and several hours later I had crispy onion flakes, ready to put in a jar and sprinkle on things later.  I'm thinking they will be useful in stuffing and in crackers in particular, but they may find their way into many different things....
