Blackberry Blueberry Micro-Mini Jam

Directions

1.In a 16-cup (4 L) microwave-safe bowl, combine blueberries and blackberries. Partially cover bowl with plastic wrap, leaving a gap for some of the steam to escape. Microwave on High for 3 minutes or until hot. Remove and discard plastic. Using a potato masher, crush berries.

2.Stir in sugar until dissolved.

3.Microwave, uncovered, on High for 2 minutes; stir and scrape down sides of bowl. Microwave on High again for 2 minutes; stir and scrape down sides of bowl. Repeat in 1-minute intervals for another 2 to 4 minutes, or until jam froths up and thickens; stir and scrape down sides each time.

4.Test for setting point. Microwave in additional 1-minute intervals as needed.

5.Remove from microwave. Stir slowly until foam subsides; skim off any remaining foam.

6.Ladle into clean jars; wipe rims. Apply metal lids and rings or use plastic lids; tighten until snug. Transfer to a towel-lined surface and let rest at room temperature until set. Refrigerate for up to 3 weeks.

Tip:
A heat-resistant silicone spatula is great for scraping down the sides of the bowl when stirring.
