Daniel Heinrich has worked at Lumiere restaurant in Boston. He’s been the bread baker at Tiqa, a Mediterranean restaurant in Portland, and has cooked at EVO and Petite Jacqueline.

Now he’s the administrative coordinator at Temple Beth-El, but he has not left his food skills behind. Heinrich has created a Friday “Pop-Up Challah Shop” at the Portland synagogue, where he makes 20 pounds of kosher challah every week. Proceeds support the synagogue’s programs.

Here’s how it works:

• The ordering deadline is end of day Thursday. You can place orders by email, phone or Facebook. Email office@tbemaine.org or call (207) 774-2649 ext. 201 and leave a voice mail.

• Customers who are not members of the synagogue must pay upfront. A 1-pound loaf costs $3, and a 2-pound loaf costs $5.

• Pickup is between 1 and 3 p.m. Fridays at the Temple, 400 Deering Ave. (entrance on Wadsworth Street). Loaves can also be picked up at 5:30 p.m. at the start of services.

• The Pop-Up Challah Shop will also be at the grand opening of the Jewish Community Alliance at 1342 Congress St. from 2 to 4:30 p.m. Sept. 10, where Heinrich plans to sell peanut butter-and-jelly and Nutella-banana sandwiches on challah rolls.
