Ingredients for Green Tomato Sauce Recipe Uk
Nine simple ingredients transform green tomatoes into this British-inspired tangy sauce.
| Ingredient | Amount | Notes |
|---|---|---|
| Green Tomatoes 🍅 | 2 lb | Unripe, chopped coarsely |
| White Onion 🧅 | 1 whole | Peeled and finely diced |
| Apple Cider Vinegar 💧 | ¾ cup | 5% acidity preferred |
| Granulated Sugar 🍚 | ½ cup | Adjust to taste preference |
| Golden Raisins 🍇 | ½ cup | Chopped for texture |
| Mustard Seeds 🌿 | 1 tbsp | Yellow or brown variety |
| Ground Ginger 🌶️ | 1 tsp | Freshly ground preferred |
| Ground Allspice 🌿 | ½ tsp | Key for British flavor |
| Salt 🧂 | 1 tsp | Sea salt preferred |
Green tomatoes are the star here—hit up farmers markets or your own garden for the unripe ones (the firmer, the better). For the vinegar, Branston or Sarson’s apple cider vinegar works perfectly and is easy to find at any Tesco or Sainsbury’s. The raisins add sweetness to balance the tang, so don’t skip them. I always grab the golden ones, but regular will do in a pinch.
No green tomatoes? Underripe red tomatoes work but cook them less so they don’t turn mushy. Swap the raisins for dried apricots if that’s what you’ve got. The allspice is non-negotiable for that authentic British kick, but a pinch of cloves can stand in if needed. Sugar can be reduced, but the vinegar’s sharpness needs balancing—taste as you go.
This keeps for 6-12 months in sterilized jars once sealed. Store in a cool, dark cupboard. Once opened, keep it in the fridge and use within 1 month. Perfect for gifting—just tie a cute ribbon around the jar.

Step-by-Step Instructions for Green Tomato Sauce
Here’s the method I use to make this tangy British-inspired creation every time.
Step 1: Prepare and Combine the Vegetables
Start by coarsely chopping the 2 lb Green Tomatoes and finely dicing the 1 whole White Onion. I prefer to keep the tomato pieces slightly uneven for a rustic texture. Transfer both to a large, heavy-bottomed saucepan.
Add the 0.5 cup Golden Raisins (chopped) and 1 tbsp Mustard Seeds to the pan. These will plump and soften as they cook, adding sweetness and a subtle crunch. Stir everything together gently—you want to combine without breaking down the tomatoes too much.
Step 2: Add the Spices and Liquid
Measure out the 0.75 cup Apple Cider Vinegar, 0.5 cup Granulated Sugar, 1 tsp Ground Ginger, 0.5 tsp Ground Allspice, and 1 tsp Salt. Pour the vinegar and sugar into the saucepan first, then sprinkle the spices and salt evenly over the top.
The vinegar’s acidity will begin to break down the tomatoes immediately, while the spices bloom in the warm liquid. I always use freshly ground ginger and allspice for the most vibrant flavor—this is where the British-inspired character really shines.
Step 3: Simmer Until Thickened
Place the saucepan over medium heat and bring the mixture to a gentle boil. Stir frequently to prevent sticking, especially as the sugar dissolves. Once boiling, reduce the heat to low and let it simmer uncovered for 45-60 minutes.
You’ll know it’s ready when the sauce has thickened significantly and the tomatoes have broken down into a chunky, jam-like consistency. The color will deepen from bright green to a rich, olive tone. Stir occasionally and taste as you go—if you prefer it sweeter, add a bit more sugar, though I’ve found the balance here is just right.
Step 4: Cool and Store
Remove the saucepan from the heat and let the sauce cool to room temperature. It will continue to thicken as it cools. I like to give it a final stir once it’s no longer steaming to ensure all the flavors are evenly distributed.
Transfer the sauce to clean, sterilized jars. It will keep in the refrigerator for up to 3 weeks, and the flavors will deepen over time. For longer storage, process the jars in a water bath for 15 minutes to preserve it for up to 6 months.
Pro Tips For Making Green Tomato Sauce Recipe Uk
- Simmer Low and Slow: I learned this the hard way—boiling the sauce too hard turns it bitter. Keep it at a gentle simmer for at least 45 minutes to let the green tomatoes break down and the raisins plump up properly.
- Soak the Raisins: Sounds weird, but it works: cover the golden raisins in warm apple cider vinegar for 10 minutes before cooking. They’ll soften faster and distribute their sweetness evenly through the sauce.
- Peel the Tomatoes: Skip the skin—it can make the sauce unpleasantly tough. Score the green tomatoes, blanch in boiling water for 30 seconds, then ice bath and peel. Yes, it’s extra work, but the texture is worth it.
- Balance the Vinegar: After burning a batch by adding all the vinegar at once, I now add it in two stages: half at the start, then taste and adjust with the rest at the end. The sugar will mellow it, but you can’t take it out once it’s in.
Make-Ahead Tips for green tomato sauce recipe uk
Prep Ahead
Chop the 2 lb Green Tomatoes and 1 White Onion the night before, storing them in separate airtight containers in the fridge. This saves time and lets the tomatoes soften slightly for easier cooking the next day.
Measure Ingredients
Pre-measure the 0.75 cup Apple Cider Vinegar, 0.5 cup Granulated Sugar, and spices into small bowls. I use a digital kitchen scale for precision with the 0.5 tsp Ground Allspice and 1 tsp Ground Ginger. 💡
Sterilize Jars Early
Wash your jars and lids in hot, soapy water, then boil them for 10 minutes to sterilize. Let them dry upside down on a clean towel. This ensures they’re ready for immediate filling once the sauce is done.
Double the Batch
If you’re making this for gifts, double the recipe. The sauce freezes beautifully for up to 3 months in freezer-safe jars. Just thaw overnight in the fridge before using.
Flavor Development
For deeper flavor, let the chopped tomatoes and onion sit with the 1 tbsp Mustard Seeds and 0.5 cup Golden Raisins for 1 hour before cooking. This extra step enhances the complexity of the sauce. 🔥
Quick Cleanup
Line your saucepan with a silicone mat or parchment paper for easier cleanup. The sauce’s natural acidity can be tough on cookware, so this simple trick saves scrubbing time.

Frequently Asked Questions
Can I use red tomatoes instead of green?
Yes, but use underripe red ones and reduce cooking time to 30 minutes to prevent mushiness. The flavor will be less tangy, so add an extra 2 tablespoons of vinegar.
How do I adjust the sweetness?
Start with 0.5 cup sugar, then taste after 30 minutes of simmering. Add more in 1 tablespoon increments until balanced. The raisins also add natural sweetness.
Why did my sauce turn brown?
This is normal! The natural sugars caramelize during the 45-60 minute cook. For brighter color, reduce heat slightly and stir more often.
What’s the best way to store it?
Use sterilized jars and process in a water bath for 15 minutes for shelf-stable storage. Once opened, refrigerate and use within 1 month.
