Peas please!

Today Christian and I planted sweet peas. I've never tried them before, so we'll see how they do. I bought little starts at the Deeps and a cute little trellis in hopes they they'll grow into bountiful, delicious vines. Yes, my hopes are probably a little high. I don't even know what I'm supposed to do with them when they do grow! How do you know if they're sugar snap peas or the kind you have to shuck? I guess you take a bite out of the pod and if it's gross you shuck it? I checked out the Western Garden Book in hopes of answering some of my myriad gardening questions. Now, if only I had a garden . . .
