How to make Fermented Green Tomatoes

Firm green tomatoes fermented in a dill-and-garlic brine until tangy and savoury. Expect about 20 minutes of active prep, then 7-14 days of fermentation, with a taste check to decide when to refrigerate.

Quick answer

Prepare the tomato wedges, mix the brine, and pack everything into a clean jar with the tomato wedges fully submerged. After 3 days, make sure the tomato wedges stay submerged and look for the first signs of fermentation. After 7 days, taste the tomato wedges and decide whether to refrigerate now or let them keep fermenting. After 14 days, do a final taste check, then refrigerate the tomato wedges in their brine.

Safety

  • Keep the tomato wedges fully submerged below the brine throughout fermentation.
  • Use non-iodized salt and non-chlorinated water for a more reliable ferment.
  • A clean sour smell is normal. A rotten smell, slimy brine, or fuzzy mold means the batch should be discarded.

Step-by-step

Day 0

Step 1: Prepare and pack

Prepare the tomato wedges, mix the brine, and pack everything into a clean jar with the tomato wedges fully submerged.

  • Set up clean equipment Wash the jar, weight, bowl, and any utensils before you start.
  • Cut tomatoes Cut the green tomatoes into firm wedges.
  • Mix brine Dissolve the salt fully in the water before pouring it over the tomato wedges.
  • Pack jar Pack the tomato wedges with the aromatics, pour in the brine, and keep everything below the surface.
Day 3

Step 2: Check fermentation

Make sure the tomato wedges stay submerged and look for the first signs of fermentation.

  • Check submersion Press any floating tomato wedges back below the brine if anything has shifted upward.
  • Check activity Look for a few bubbles, slightly cloudy brine, or a fresh sour smell.
  • Check aroma The jar should smell fresh and fresh, dill-and-garlic rather than rotten.
Day 7

Step 3: Taste and decide

Taste the tomato wedges and decide whether to refrigerate now or let them keep fermenting.

  • Taste Lift out a piece with a clean fork and judge the balance of salt and tang.
  • Resubmerge and cover Return the tomato wedges below the brine before continuing the ferment.
Day 14

Step 4: Finish and store

Do a final taste check, then refrigerate the tomato wedges in their brine.

  • Taste final batch Confirm the tomato wedges are as tangy as you want before ending room-temperature fermentation.
  • Refrigerate Seal the jar and refrigerate the tomato wedges in their brine to slow the fermentation.

What to look for

  • Day 0: The tomato wedges are fully covered by brine and held down with a weight. That gives the batch the best chance to ferment cleanly and stay mold-free.
  • Day 3-4: The brine looks slightly cloudy and you may see a few small bubbles. Those are normal early signs that fermentation has started.
  • Day 7 and beyond: A piece tastes lightly sour, firm, and savoury. Use taste to decide whether to refrigerate now or ferment a few more days for more tang.

Troubleshooting

  • The brine does not cover the tomato wedges. Some liquid was lost or the pack was loose. Top up with a 3 percent salt solution until everything is covered again.
  • No bubbles appear after a few days. The room is cool or fermentation is starting slowly. Give it another day or two and rely on smell and taste as well as visible bubbles.
  • A piece floats above the brine. The weight shifted or the jar was packed loosely. Push it back down, adjust the weight, and make sure all solids stay submerged.
  • It tastes too salty early on. The ferment is still young or the brine ran slightly strong. Let it ferment a little longer before judging, then serve with unsalted foods if needed.
  • They still taste sharp and raw. Green tomatoes take time to mellow. Ferment a few more days and taste again before refrigerating.

Storage

Seal the jar and refrigerate once it tastes balanced to you, keeping the tomato wedges below the brine. It will continue to mature slowly in the cold.

Shelf life: about 1-2 months refrigerated
