Calling them einkorn “berries” makes this a salad.
Kidding of course, but it looks delicious! As for planting einkorn “seeds,” if the einkorn you purchased from your local co-op is whole grain and not treated in any way you can probably just plant it (not vouching for the legitimacy of the info on this site, but it seems straightforward enough): https://farmandanimals.com/how-to-grow-einkorn-wheat/
What I would probably do is try to sprout a few einkorn berries to see how viable they are. If you get a certain amount of it to sprout then I would just buy more einkorn and sow it. You don’t really need any special equipment for sprouting - a jar or a tray and some paper towels should do it. I’ve purchased Sprout People’s sprouting cups and use their reference material previously: https://sproutpeople.org/pages/growing-sprouts
Either way, it’s great that you’re appreciating an “ancient” wheat. Good luck turning your lawn into a wheat field. Keep us posted!
