Homemade Guava Jam

During guava season, my Mom makes this homemade Guava Jam every week. It’s sweet, sultry and tropical, cans beautifully and makes a great food gift. If you’re looking for guava recipes, jam is a great place to start.  You can stir it into yogurt, spread it on toast or top a piece of poundcake with this easy guava jam recipe.

What is guava?

Guavas are tropical and subtropical fruit with distinctly aromatic perfume and a musky sweet flesh. There are many varieties of guava including apple guava and lemon guava, both with pale yellow flesh. This variety is primarily found in Mexico and South America.

Another type is the strawberry guava, with a yellowish-pink hue and fruit that can grow as large as a softball. These orbs have a bright pink interior and a lushly sweet, tropical, slightly musky flavor and they make the best guava jam.

My mother’s strawberry guava tree produces copious amounts of fruit when its in season. So much so that the branches will get so heavy that they bend down to the ground under the weight of it.

Consequently, she spends the better part of the summer making batch after batch of this guava jam recipe. It’s a favorite with my nephew, Palmer, who gets his own jar – so he doesn’t have to share with anyone else.

Why you’ll love this recipe:

• It has less sugar than most jams, so it’s not overly sweet, but is perfectly balanced.
• Making homemade guava jam is easy and only takes about 45 minutes to prep and cook the fruit.
• This recipe is scaleable based on how many guavas you have; make a lot or a little.
• It’s a perfect recipe for canning and extends the shelf-life of guavas for a year.
• Homemade Guava jam makes a terrific food gift for the holidays.

Guava season

July and August are guava season here in South Florida, and my Mom’s guava tree is loaded with them. She’s at war with the iguanas to snatch them off the branches before they can reach the tropical fruit.  

There are other invading critters, too — which she’s successfully deterred through organic farming methods (see description and photos at the end of this post).

Guava ripens one fruit at a time, so my mother picks anywhere from 8-10 guavas daily during the season. Consequently, she’s developed a very efficient system for processing them, which I’m happy to share with you.

Quick way to prep guavas for homemade jam:

1. Peel the guavas using a vegetable peeler or sharp knife.
2. Cut them in half, crosswise.
3. Scoop the seeds from the center using a spoon (or Mom recommends a melon-baller).
4. Then cut the guavas into quarters and transfer the fruit to a food processor.
5. Pulse to your desired texture. We like it slightly chunky (as shown below), but if you like a finer texture, run the machine for longer.

Now you can use the guavas to make jam or other recipes.

Make ahead

If you want to put it off til later, the peeled and seeded fruit freeze well too. Just bag the processed guavas in freezer-safe zip-top bags and fill your freezer to make your favorite guava recipes anytime.

Another way to process guavas:

If you’re short on guavas and want to get the most yield from your fruit, here’s another way to use up all the fruit, including the meat around the seeds.

• Slice the guavas in half, crosswise, scoop out the fruit (seeds and all) with a spoon and transfer to a bowl.
• Mash the fruit with a potato masher to break up the guava.
• Transfer the guava pulp and seeds to a blender and pulse 3-4 times to loosen the seeds from the fruit. You don’t want to puree it; just 1-2 second pulses until the seeds break away from the guava pulp.
• Transfer the guava to a mesh strainer and press on the fruit with the back of a spatula to force it through the filter. Discard the seeds. This makes a very finely textured guava puree.

How to make guava jam:

1. Measure out your guava puree to determine how much fruit you have. You’ll use half as much sugar than you have fruit… So if you have 4 cups of puree, you’ll need 2 cups of sugar.
2. Add the guava puree to a large saucepan and top with the sugar.
3. Place the pot over medium-high heat and bring to a boil, stirring regularly.
4. Once the fruit is boiling, add a split vanilla bean or vanilla paste (if using) and 1½ tablespoons of liquid pectin for each cup of fruit—4 cups of fruit requires 6 tablespoons of liquid pectin.
5. Cook the guava jam mixture, stirring constantly for 20 minutes.
6. Remove from the heat and transfer to glass canning jars.
7. If you’re not canning the guava jam, transfer it to the refrigerator, keeping it fresh for several weeks to a month. You can also seal the jam in a food-safe manner by water-canning, which we do (see canning instructions in the recipe card below).

Variation:

• I use a little vanilla bean paste in the guava jam recipe to give it a mellow flavor. However, you can switch it up by adding lime juice to the guavas for a tangy freshness. Squeeze the juice of one lime and a teaspoon of the zest into the pot as you cook the jam.

FAQ’s

If you’ve never done home canning, I recommend getting some basic canning equipment to make the process easier.

Helpful canning tools you’ll need:

• A large canning pot or stock pot. It should be large and deep enough to fit multiple jars and cover them with water by at least 1″. I use my largest stock pot, but you can also use a pot designed for bulk canning, which comes with a rack to elevate the jars off the bottom of the pot.
• A rack to elevate jars from the bottom of the pot (if you’re using a plain stock pot not equipped with a rack).
• Canning Kit – which includes a wide-mouth funnel (for filling canning jars), a jar wrench (for holding the hot jar while you screw on the lid), a bubble remover to eliminate air pockets in your guava jam, magnetic lid lifter (to retrieve the flat lids from a pot of boiling water without scalding yourself), jar lifter (to retrieve canning jars from boiling water).
• Canning jars with lids and rings – Canning jars can be reused so long as there are no cracks or chips in the glass.
• Lids and rings cannot be reused once you’ve canned with them, so you’ll need replenish each time.

What to do with guava jam:

• Spread it on your morning toast or muffins.
• Swirl it into yogurt, overnight oats or into your morning smoothies.
• Sandwich between sugar cookies.
• Make a tropical trifle dessert layering rum-soaked pound cake slathered with guava jam and layered with custard and whipped cream.
• When making big batches of jam, I recommending gifting them to friends and family. They make great hostess gifts and stocking stuffers.
• My mother sells her homemade guava jam at her garden club for their fundraising activities. It’s always the first thing to sell out.

 How to grow organic guavas on your tree and foil predators

My Mom not only battles the iguanas, but she has another nemesis… Caribbean fruit flies.

They like to burrow tiny pinholes in the guava and lay their eggs in the fruit as it develops on the tree.

Once hatched, the pupa devours the fruit from the inside. She would pick her guavas and slice them in half only to see wriggling white worms. Once you’ve seen that, there’s no way you’ll eat the fruit.

After receiving expert advice from horticulturalists, nurseries and googling endlessly, my Mom found an “organic” solution to the insidious fruit flies.

She wraps each fruit as it’s just starting to bud with peds – you know those little foot hosiery that you wear to try on shoes? The fine web of hosiery prevents the insects from laying their eggs in a 100% organic way.

Mom keeps boxes of the peds and sets out every day to wrap individual guavas when they’re no bigger than a grape. As the guavas grow, the peds stretch with the fruit and protect it from invaders (see photo below).

The result is organic guavas for us with no insects and the iguanas get whatever fruit she didn’t wrap.

Bonus: After giving the guava tree this extra treatment for several seasons, the fruit flies became conditioned to the fact they couldn’t lay their eggs, and now they’ve left even the unwrapped fruit alone!
