Hey guys! I’ve got a great guest post today from Andrea Dekker of Simple Organized Living. She is one of my blogging friends here in West Michigan and she is so kind to share some of her simple cooking secrets over here. Enjoy her post, and don’t forget to check out her site – she’s got some great trips and tricks for simple organized living!

Yes, I know it’s only March and fresh berries definitely aren’t in season yet, at least not in Michigan. However, I did see the very first batch of rhubarb at the grocery store — so spring is almost here!

One of my favorite things about spring and summer is making homemade jam. I make 6 or 7 different varieties of jam for us to enjoy, and to give as gifts all year long — it’s the perfect hostess or teacher gift along with a loaf of Megan’s delicious homemade bread!

I know that home canning is often perceived as extremely difficult, tedious, and time-consuming — but canning jam is one of the easiest foods to start with. And this simple microwaveable recipe is almost fool-proof.

You don’t need any traditional canning equipment, you only need a few cups of berries, and it only takes about 20 minutes from start to finish!

If you’ve ever wanted to try home canning, THIS is the way to start.


Simple Microwave Jam

Yield: Makes about two 8-oz. jars


  • 2-1/2 c. mashed fruit -- berries are a great way to start (you can use
    either fresh or frozen fruit that has been defrosted)
  • 1 T. lemon juice
  • 2 T. powdered pectin
  • 2 c. granulated sugar


1. In a large microwave-safe bowl, combine mashed fruit and lemon juice.

2. Stir in pectin until dissolved, then stir in sugar.

3. Microwave uncovered on high for 2 minutes. Stir and scrape sides of the bowl.

4. Return bowl to microwave for 2 more minutes. Stir and scrape sides.

5. Repeat in 1-minute intervals for another 2 to 4 minutes, or until jam froths up and thickens -- stirring and scraping the sides in between each interval.

6. Once the jam is thick, remove from microwave.

7. Stir slowly for 2 to 3 minutes or until foam subsides. You can skim off any remaining foam if you don't want it to cloud your jam (it won't affect the taste at all).

8. Ladle jam into clean jars or plastic containers and cover with tight-fitting lids.

9. Let rest at room temperature until set, then refrigerate or freeze.

10. Once refrigerated, the jam should last for 2-3 months. It will last much longer if frozen.

It doesn’t get much easier than that.

If for some reason, your jam doesn’t thicken or set properly, you can always use it as a yummy ice-cream topping!

A Few More Tips:

1. It’s best to use wooden or plastic spatulas, and bowls (metal is not ideal)

2. It’s best to use a 1200-watt microwave with a turntable. If wattage is higher, cook on 70% power; or if wattage is
lower, cook for longer.

3. Follow all measurements and instructions. Making jam is a simple process as long as you follow the
rules. It’s pretty important to measure all the ingredients carefully and cook for the
right amount of time. And NEVER try to reduce the amount of sugar!

4. Don’t make double or triple batches. If you want more jam, you’ll most likely achieve better results by making multiple single batches instead of making one huge double/triple batch.

5. Don’t worry about the jars sealing properly. Since this recipe makes such a small batch, you can simply store
your jam in the fridge until it’s gone. And if you don’t think you’ll eat it all in a few
months, you can put some in the freezer for later.
