Ohhhhh y’all. After I came back from vacation, I found myself staring down about 30 pounds of tomatoes that were ready right-freaking-then. Thus ensued days and days of canning.
Though I also made vats of marinara and vodka sauce base, the majority of that week’s harvest went toward Bear’s favorite recipe: Roasted Tomato-Lime Salsa. This recipe comes from one of my top four canning resources, Foolproof Preserving from America’s Test Kitchen. I love this book for clarity of instruction, and the “whys” of the steps. And, in general, any ATK recipe has thorough research behind it.
Some quick notes before I share the recipe:
- If you need a basic knowledge of canning, the ATK book, and the Ball Blue Book are excellent guides. The Ball Blue Book is where I started, and I think it’s a staple resource that belongs in every kitchen. If you are a canning newbie, get your mitts on one. Also, America’s Test Kitchen’s site is a treasure trove if you need tested techniques on pretty much anything.
- This recipe calls for commercially bottled lime juice. Don’t clutch your foodie pearls, there’s a reason for that. Fresh limes can vary wildly in their pH, while bottled juice remains consistent. The pH is what keeps the food safe, so unless you want to become a human science experiment, follow the recipe.
- Speaking of which, FOLLOW THE DANG RECIPE. Canning recipes are literally science-based, tested procedures that safely preserve food. This isn’t the time for “a little of this…some of that…”
- This recipe can be doubled. Just broil the veggies in batches, and simmer it a little longer, like 20-25 minutes.
- Remember that all broilers and stovetop burners vary astronomically in output. This is the time you need to be a wee bit more observant, rather than trusting a recipe time range. Never leave a broiler unattended, unless you are hell-bent on meeting your local firemen.
Roasted Tomato-Lime Salsa (Canning)
Ingredients
- 2-1/2 pounds Roma tomatoes cored and halved
- 1 onion sliced into 1/2 thick rounds
- 5 jalapenos stemmed and halved lengthwise
- 6 cloves garlic peeled
- 1/3 cup bottled lime juice
- 2-1/2 tsp salt
- 2 tsp sugar
- 2 tsp chopped fresh cilantro
- 1 tsp ground cumin
Instructions
- Get your canning set-up arranged with jars sterilized and simmering in your water bath canner, lids hanging out in warm water, and all your gear together.
- Cover a sheet pan with foil and place tomatoes and onions, cut side down on it. Broil the veggies until the tomatoes are well charred (anywhere from 10-15 minutes). Remove the pan from the oven and offload the veggies into a bowl. Add the jalapenos, cut side down, and garlic to the empty sheet pan and broil until jalapenos are also charred, 8-10 minutes.
- Transfer the jalapenos, garlic, half of the tomatoes, and half of the onions to food processor and pulse until it's a thick puree. Transfer to Dutch oven. Transfer remaining broiled tomatoes and onions to the food processor and pulse into ½-inch pieces, 2 or 3 pulses; add to Dutch oven.
- Stir in lime juice, salt, sugar, cilantro, and cumin. Boil over medium-high heat, stirring often, until salsa has thickened slightly, probably 8-15 minutes depending on your stovetop.
- Ladle the hot salsa into the hot jars, leaving ½ inch headspace. Use a wooden skewer or popsicle stick to remove air bubbles. Wipe rims clean, top jars with warm lids, screw on bands until fingertip tight, and return jars to canner.
- Bring water in canner back to a boil. Process jars for 15 minutes for up to 1,000 feet, 20 minutes for 1,001 to 3,000 feet, 25 minutes for 3,001 to 6,000 feet, or 30 minutes for 6,001 to 8,000 feet. Remove jars to a cooling rack and let sit undisturbed for at least 8 hours. Check seals and store. If any failed to seal (hey it happens to even the most experienced canner), grab some chips and have a movie party. Don't forget to label them, and you can decide yourself if sharing is caring. According to Bear, that would be hard no.
