Indian Jujube? The pictures look more like dates. In anycase, I found some recipes too. There's beyr cake recipe too! I would never have known there were other ways to eat beyr apart from pick off tree and eat. I feel so primitive.
I think I'll try this one next time I'm in Pakistan:
Jujube Syrup
Boil syrup remaining from the *Candied Jujubes, uncovered, until reduced to about 2 cups. Use over pancakes and waffles. Store in the refrigerator.
Other uses: Substitute the dried jujube wherever recipes call for raisins or dates. Dried jujubes are a wonderful snack that can be prepared without the use of any preservative as is so commonly needed for other dried fruits.

*Candied Jujubes
Wash about 3 pounds dried jujubes; drain and prick each several times with a fork. In a kettle bring to a boil 5 cups water, 5-1/2 cups sugar, and 1 tablespoon corn starch. Add the jujubes and simmer, uncovered, stirring occasionally, for 30 minutes. Cool, cover, and chill overnight.
The next day bring syrup and jujubes to a boil and simmer, uncovered, 30 minutes. With a slotted spoon lift jujubes from syrup and place slightly apart on rimmed pans. Dry in oven, or in sun for about 2 to 3 days. Check fruit frequently and turn fruit occasionally until the jujubes are like the dates ones sees in the market.
