Ingredients

2 pounds fresh tomatillos (about 12-15 medium), husked and rinsed
2 cups granulated sugar
1/4 cup fresh lime juice (about 2 limes)
2 tablespoons lime zest
1 large green apple, peeled, cored, and grated
1/2 teaspoon kosher salt
1/2 teaspoon ground cinnamon
1/8 teaspoon ground cloves
1/2 teaspoon vanilla extract
1 jalapeño, seeded and finely diced (optional, for a mild kick)
1 packet (1.75 oz) fruit pectin (optional, for a firmer set)

Instructions

Prepare the tomatillos: Remove the papery husks from the tomatillos and rinse off the sticky residue. Chop the tomatillos into 1/2-inch pieces.
Combine ingredients: In a large, heavy-bottomed saucepan, add the chopped tomatillos, grated apple, sugar, lime juice, lime zest, salt, cinnamon, cloves, and jalapeño (if using). Stir well to combine.
Maccerate: Let the mixture sit for 15 minutes. This helps the sugar draw out juices from the fruit and starts breaking down the tomatillos.
Cook the jam: Place the saucepan over medium-high heat. Bring the mixture to a gentle boil, stirring frequently to prevent sticking. Reduce heat to medium and simmer, uncovered, for 30–40 minutes. Stir occasionally and use a potato masher to help break down the tomatillos as they soften.
Add pectin (optional): If you prefer a thicker jam, stir in the fruit pectin according to the package instructions about 10 minutes before the end of cooking. Continue to cook for another 5–10 minutes, stirring constantly.
Check for doneness: The jam is ready when it thickens and a spoonful placed on a chilled plate gels after a minute. If it runs, cook for a few more minutes and test again.
Finish and flavor: Remove the saucepan from heat. Stir in the vanilla extract.
Jar the jam: Ladle the hot jam into clean, sterilized glass jars, leaving about 1/4 inch of headspace. Wipe the rims and seal with lids. Allow to cool to room temperature before refrigerating for short-term storage. (For shelf-stable storage, process in a boiling water bath only if your jam’s pH is below 4.6; otherwise, refrigerate or freeze.)
Chill and set: Refrigerate the jam for at least 4 hours, ideally overnight, to allow it to fully set and for the flavors to develop.

Tips

Substitutions: If you don’t have lime, substitute with lemon juice and zest for a slightly different citrus note. Honey or agave can replace up to half the sugar for a more floral sweetness, but avoid reducing sugar too much or the jam may not set properly.
Common mistakes: Don’t skip the maceration step; it helps prevent burning and ensures even cooking. Avoid overcooking, which can cause the jam to become too thick or caramelized.
Texture tips: If you like a smoother jam, use an immersion blender to puree the mixture before jarring (after cooking). For a chunkier texture, mash only lightly with a potato masher.
Storage safety: Only can this jam for shelf storage if you’ve tested the pH and it is safely acidic (below 4.6). Otherwise, store in the refrigerator or freezer to prevent spoilage.

Serving Suggestions

Spread on warm toast, English muffins, or bagels for a tangy breakfast treat.
Serve as a condiment with grilled chicken, pork, or fish to add a sweet-and-sour accent.
Pair with soft cheeses like goat cheese, brie, or cream cheese on crackers for a vibrant appetizer.
Use as a glaze for roasted vegetables or as a topping for tacos and quesadillas.
Swirl into yogurt or oatmeal for a fruity, unexpected twist.

Variations

Spicy Tomatillo Jam: Increase the jalapeño, or add a serrano or habanero pepper, for a hotter version. Always wear gloves when handling hot peppers.
Herb-Infused: Add 2 tablespoons of chopped fresh cilantro or mint during the last few minutes of cooking for a refreshing herbal note.
Citrus Swap: Substitute orange juice and zest for the lime for a softer, sweeter citrus undertone.
Berry Boost: Stir in 1/2 cup of chopped fresh strawberries or raspberries during cooking for a jam with a pink hue and an extra layer of flavor.
Alcohol Infusion: For a grown-up twist, stir in 2 tablespoons of tequila or triple sec at the end of cooking (after removing from heat).

Storage and Reheating

Tomatillo jam will keep in the refrigerator for up to 3 weeks when stored in a clean, airtight jar. For longer storage, freeze jam in freezer-safe containers for up to 6 months. Thaw overnight in the refrigerator before using. If you wish to can the jam for pantry storage, you must ensure the pH is below 4.6 (test with a pH meter or strips); otherwise, refrigerate or freeze only. To reheat (if you prefer warm jam), spoon the amount you need into a small saucepan and warm gently over low heat, stirring frequently, until just heated through. Avoid boiling or prolonged heating, as this can alter the texture and flavor.

Frequently Asked Questions

Can I make tomatillo jam without pectin?
Yes, you can make tomatillo jam without added pectin. Tomatillos and apples both contain natural pectin, which helps the jam set. However, if you prefer a firmer, more traditional jam texture, adding commercial fruit pectin ensures a reliable set, especially if you reduce the sugar or add extra ingredients.
How do I know when the jam is ready?
The jam is ready when it thickens and coats the back of a spoon. For a more precise check, place a small dollop on a chilled plate and let it sit for a minute; if it wrinkles when you nudge it, it’s set. If it’s still runny, continue cooking and test again after a few minutes.
Can I water-bath can this jam for shelf storage?
Only if you are certain the jam is high-acid (pH below 4.6), which is typically achieved with enough lime or lemon juice. Tomatillos are lower in acid than many fruits, so always test the pH before water-bath canning. If the pH is above 4.6, store the jam in the refrigerator or freezer instead to prevent botulism risk.
Is this jam very spicy?
The base recipe is mildly spiced, with jalapeño adding just a gentle kick. You can omit the jalapeño for a completely mild jam, or increase the quantity or use hotter peppers if you like more heat.
What if my jam is too runny after cooling?
If your jam is still runny after chilling, you can return it to the saucepan and simmer for another 5–10 minutes to evaporate more liquid. Alternatively, add a bit more pectin and cook briefly. Remember that jam thickens further as it cools, so don’t judge the final texture until it’s fully chilled.
Can I use frozen tomatillos?
Yes, frozen tomatillos work well for this recipe. Thaw them completely and drain excess liquid before chopping and cooking. The texture may be a bit softer, but the jam will still set nicely.
