What does a plum look like?

In the brief guide, we are going to answer the question ‘What does a plum look like’ with a detailed analysis of what are the safety measures to keep in mind when preparing it.

What does a plum look like?

Plums are stone fruits that can be oval or round in shape. They can have skin that is black, purple, red, or yellow. Plum flesh is soft and juicy on the inside, and it is usually an amber color. Prunes are made from dried sweet black plums.

How do you know if a plum is ripe?

Hold a plum in your palm with the bottom of the fruit down to see if it’s good. It should be quite heavy for its size.

When you close your hand around the plum, your palm should have a slight softness to it; not mushy, just a gentle give. As you curl your fingers further, the fruit should firm up and feel more substantial towards the stem. If the plum is too soft, it has most likely passed its prime.

If you are not going to eat your prize plums right away, buy some that are still a little firm. They will go from green to perfectly ripe in one or two days if placed in a brown paper sack at room temperature. 

When ripe, what color is a plum?

There is no specific color that indicates when a plum is ripe. Plums are available in nearly every color of the rainbow, ranging from an almost white lite green to a deep purple that frequently appears black.

Look for a white powdery substance that easily wipes or washes off smooth skin. This powder indicates that the fruit is ripe and has not been overworked.

Is it safe to eat overripe plums?

Yes, overripe plums are safe to eat as long as they haven’t begun to rot or mold. In fact, depending on the variety, they are sweetest when they are at the very edge of usability.

Overripe but not rotting plums are ideal for smoothies, jellies, and baking.

What is the shelf life of plums? 

It depends on storage conditions; after purchasing, keep plums in a dry area. Plums will become fully ripe in about 2 to 3 days if properly stored at room temperature.

How can you speed up the ripening of plums? 

Put plums in a brown paper bag, seal it, and place it on the counter to ripen.

Refrigerate plums until fully ripe; allowing plums to ripen at room temperature results in more flavorful, juicy plums.

Refrigerate fully ripe plums to extend their shelf life; for best results, bring the plums back to room temperature before using.

How long do plums keep in the fridge?

Fully ripe plums will keep in the fridge for 3 to 5 days.

Is it possible to freeze raw plums? 

Yes, wash and leave whole or cut in half or quarters with the pit removed. In a saucepan, combine 2 3/4 cups sugar and 4 cups water, mix until the solution is clear, and bring to a boil. Allow the syrup to cool before pouring it over the plums and then store the plum.

How long can you keep plums in the freezer? 

They will keep their best quality for about 10 to 12 months if properly stored, but will be safe for much longer. The freezer time indicated is for best quality only; plums kept constantly frozen at 0°F will keep indefinitely.

How can you tell if your plums are bad or spoiled? 

Plums that are spoiling will typically become very soft, develop dark spots, and begin to ooze; discard any plums that have mold or an off smell or appearance.

How to make plums?


  • sugar
  • orange
  • cinnamon
  • Flour
  • Butter
  • almond


Preheat the oven to 350°F and place the plums in the bottom of a shallow gratin dish. Sprinkle the plums with the sugar, orange zest, cinnamon, and flour mixture. Flow over water.

In a food processor, combine all of the crumble ingredients and pulse until the mixture just begins to clump together. At this stage, take care not to overprocess. Alternatively, rub the butter into the flour with your hands before stirring in the remaining ingredients.

Scatter the crumble over the plums and bake for 30–40 minutes, or until golden brown. Allow for 15 minutes before serving with custard or cream.
