The first time I tried to make strawberry jam, I thought it was idiot-proof: strawberries, sugar, boil it, jar it. Done.
Wrong.
I ended up with a runny, sad syrup that slid off my toast like an oil slick. Worse? I burned a batch because I turned away for 30 seconds.
What saved me was studying Gordon’s technique—the focus on sugar balance, temperature, and simple sensory tests.
Today, you’re not just getting a jam recipe. You’re getting control: how to master the set, the flavor, and the shelf life.
Why This Works (And Where Most Go Wrong)
Most people fail because they either:
- Boil too aggressively, losing too much moisture too fast.
- Don’t hit the exact setting point (105°C / 221°F).
- Use strawberries with too much water content.
- Skip the plate test or misread it.
Gordon’s system fixes it by:
- Controlling sugar dissolution before high heat.
- Building a proper pectin/sugar/acid balance (even without added pectin).
- Using sensory markers (plate test, bubble size, smell) to catch the perfect moment.
What surprised me:
- Strawberry jam doesn’t naturally have a ton of pectin. That’s why the lemon juice isn’t optional—it’s structural.
Ingredients That Actually Matter
- 2 pounds (900g) fresh strawberries – Ripe but not overripe. Overripe = waterlogged, mushy jam.
- 4 cups (800g) white sugar – Not less. Not “healthier versions.” Sugar isn’t just sweetener here, it’s preservative and pectin activator.
- ¼ cup (60ml) lemon juice – Fresh squeezed. Bottled stuff can mess with pH and taste.
Mistake to avoid:
- Tried swapping white sugar for coconut sugar once—result: a brown, muddy mess with no set.
How To Make Gordon Ramsay Strawberry Jam
Hull your strawberries. No leafy bits. No white cores if they’re tough.
Mash them in batches in a wide bowl. You want small chunks left—not puree.
In a heavy-bottomed saucepan, combine mashed berries, sugar, and lemon juice.
Stir over low heat until sugar dissolves. Do not rush this.
Once dissolved, crank heat to high and bring to a full rolling boil—that means it keeps boiling even when stirred.
Cook, stirring often, until mixture reaches 105°C (221°F).
No thermometer, Watch the bubbles—they’ll look thicker, glossier, slower.
Plate Test:
Drop a spoonful on a frozen plate. Push it with your finger after a minute.
If it wrinkles, it’s done. If it runs, keep boiling.
Once set, ladle jam into hot, sterilized jars, leaving ¼ inch (6mm) headspace.
Seal tightly. Process in a boiling water bath for 10 minutes for shelf-stable jars.
Cool jars undisturbed for 12–24 hours before touching.

What Gordon Ramsay Says About This Dish
“You can’t rush flavor. You have to respect the process.”
(My takeaway: Low heat first is crucial. Don’t slam the heat early.)
“Strawberries need acidity to sing.”
(Fresh lemon isn’t just a seasoning here. It locks the jam structure.)
“Cooking is about control—know what’s happening in your pan.”
(Watching the sugar dissolve before boiling changed everything.)
“Taste everything. Constantly.”
(Spoon test the jam after boiling 10 min. Don’t just guess by time.)
What I Got Wrong (And How I Fixed It)
- Burnt sugar flavor: Tried multitasking. Jam demands 100% attention.
- Runny jam: Pulled it at 102°C thinking it was “close enough.” It wasn’t.
- Foam overload: Skipped skimming foam off the top. Bad idea—cloudy, weird-textured jam.
Variations That Actually Hold Up
- Vanilla Strawberry Jam: Add half a scraped vanilla bean at the beginning.
- Boozy Jam: Add 2 tablespoons of Chambord or Cointreau once jam is cooked but still hot. Stir in before jarring.
- Peppery Strawberry Jam: A pinch of cracked black pepper at the end brightens it shockingly well.
What ruins it:
Adding mint, basil, or too much alcohol before cooking. Will kill the pectin set.
Pro Tips That Change the Game
- Sterilizing jars properly matters: Boil for 10 minutes. Dry completely upside down.
- Test two ways: Plate test and thermometer. Belt and suspenders.
- Cooling position: Space jars 2 inches apart so air circulates evenly during cooling.
- Label the jars: Date and batch notes. You think you’ll remember—you won’t.
Storage + Leftover Moves
- Store: Cool jars at room temp up to 1 year if processed correctly.
- Fridge jam: Skip the water bath; just fridge. Good for 3–4 weeks.
- Freeze: Jam can freeze 6 months. Thaw slowly in fridge overnight.
- Reheat: Microwave a tablespoon for 5–10 seconds to soften.
FAQs
Q: Can I make this jam without a thermometer?
Yes, but it’s riskier. Use the frozen plate test religiously.
Q: Why is my jam foamy?
Natural air bubbles. Skim them off during boiling for a clear finish.
Q: Do I need to use pectin?
No—strawberries plus lemon provide enough natural pectin for this recipe.
Q: Can I use frozen strawberries?
Only if you thaw and drain them first. Too much water will wreck your set.
Q: How do I know the jars sealed properly?
The lids should “pop” inward and not flex when pressed.
