Hello! I'm preparing to receive my two new piggy boys I'm making my own pea flakes to help with bonding and need help!

1. Can I boil split peas to soften them more quickly? I've seen varying answers on this..
2. Can I dehydrate the whole (technically half.. ) split pea instead of smooshing?
3. Why is there smooshing anyway?
4. Are there any other peas you can either A) dehydrate and use or B) use without dehydrating

Thanks for your help! I know I will have more questions.

So excited to join the piggy family and will post pics once my boys arrive!
