 Roma Tomatoes FAQ’s

What is a Roma tomato?

A Roma tomato, also known as a plum tomato, is a paste tomato. Paste tomatoes, like Roma tomatoes, generally have a thicker fruit wall, fewer seeds, and a denser but more grainy flesh. Roma tomatoes tend to be oblong in shape and heavy for their size.
They also tend to be more firm than a non-Roma or paste tomato. Roma tomatoes ripen at one time rather than continue through the season. While they can be eaten raw, they are at their best when they are cooked.

How to grow Roma tomatoes?

All tomatoes need plenty of water, soil rich in organic material, and need to be staked up off the ground for the best fruit production. Roma tomatoes are not the exception.

  • Prepare the soil of your tomato bed by adding compost or a slow-release fertilizer.
  • Once you plant your Roma tomato plants, water them at least once a week.
  • Once your Roma tomato plants are 6-12 inches (15 to 30.5 cm.) high, start staking the Roma tomatoes up off the ground.

When is a Roma tomato ripe?

When dealing with Roma tomatoes, your safest bet to know if these are ripe is to focus on their color. Once the tomato is red all the way from the bottom to the top, it is ready for picking.

What is the difference between dicing other tomatoes and Roma tomatoes?

Like a Roma, dicing an oblong tomato doesn’t require you to core the tomato before setting up the dice.

Is there a special knife for dicing tomatoes?

Actually, a tomato knife is specially designed to tackle the thin skins and fragile insides of tomatoes. They are typically serrated, which allows the knife to move through the skin quickly and with minimal pressure.

Is it ok to use any serrated knife?

While serrated knives tend to cut tomatoes better than a plain edge knife (unless it is super sharp), not all serrated knives will do the trick. For instance, steak knives and other general use knives tend to be too thick to execute a paper-thin tomato slice.

Additional Tips on How to Dice Roma Tomatoes

  • The little stem end usually doesn’t amount to anything. But lopping it off won’t hurt anything either, so do whichever way you prefer. Some people don’t bother cutting off the stem, as it’s so small it’s largely unnoticeable.
  • How many slices you make depends on how small or large you want the dice to be.
  • Wash each Roma tomato under the faucet, turning it as necessary to wash the full surface and remove dirt and debris. If the Roma tomato has any stickers on it, make sure to remove these before dicing.
  • Cut the tomato length-wise to cut it in half. Cut it with one hand and hold it in place with the other. Try to keep the two halves of the tomato in roughly even sizes.
  • As Roma tomatoes are smaller than regular tomatoes, be careful when using your fingers to hold the tomato in place. Use only the tips of your fingers, and be extra careful to keep your fingers away from the knife.
  • Your goal is to keep your cuts the same length, so your diced tomatoes are roughly the same size.
