It’s easy to buy too much rhubarb when you are not sure how much you will need. As you’ve read, after storing it for a while, the rhubarb might have gone bad. Here are 4 tips to determine whether you need to get rid of it:

  • Smell: Rhubarb is a vegetable and it should smell fresh, if it smells rotten or moldy, it’s time to throw it in the trash.
  • Color: The overall color of rhubarb is ruby red, you will also find a few light green patches scattered across the stalks. If the skin starts turning brown or black, or you find dark grey patches on it, that’s a clear indication its rotten.
  • Mold: If there are a few dots of mold at the end of the stalk, you can get away with cutting it off. But once the mold starts spreading and traveling up the stalk, get rid of it. Mold typically develops in the form of small black, white or green specs. You will also find that mold manifests as white fir, you might not be able to see it, but you can feel it.
  • Texture: Fresh rhubarb should be firm when pressed. Any signs of softness or tenderness means it’s past the sell by date. If the rhubarb has turned completely mushy, no need for a touch test, that’s a sure sign its rotten and that you need to throw the stalks in the trash immediately.
  • Taste: Most people put their rhubarb in a pie, but you can eat it raw if that’s your preference. It typically has a tart taste and the stalks should be crispy. You will know if rhubarb has gone bad because there will be no crunch to it, and instead of a tart taste, it will be bitter.

The best way to ensure your rhubarb remains fresh is with proper storage, package it well and don’t leave it sitting on your kitchen counter at room temperature.

How to Store Rhubarb

Rhubarb is not like other vegetables; it is unique in its own right and there are things you will need to do before storing it. To start, rhubarb typically has leaves on it, but they are poisonous.

Some stores cut them off before putting them on display, others don’t. If your rhubarb has leaves on it, you will need to trim them as soon as you arrive home.

When it comes to storage, you can either do it at room temperature, in the fridge or in the freezer. Here are some tips on how to store rhubarb:

1. Room Temperature

If you are going to use the rhubarb within a couple of days of buying it, you can store it at room temperature. You can leave them on the kitchen counter or put them in the pantry.

It is advised that you don’t wrap them up because this traps the moisture and stops the vegetable from drying out.

As beneficial as this may sound, room temperature and moisture are not a good combination because it accelerates the bacteria growth.

2. In the Fridge

It is advised that you don’t wash the stalks before putting them in the fridge, but make sure you wrap them up first.

However, when you do wrap them, you will need to poke holes in the bag to allow for air circulation. Ethylene gas is responsible for helping fruits and vegetables to ripen, when it is trapped, the rhubarb will expire quicker than they are supposed to.

Additionally, it is just as important to keep them wrapped up because rhubarb is best kept when there is a high level of humidity, and as mentioned, the plastic helps keep moisture locked in.

It is also important to mention that if you choose to cut the rhubarb, it’s best that you store it in an airtight container; this will prevent it from getting ripe too quickly.

3. Freezing Rhubarb:

If you know in advance that you are going to freeze your rhubarb, its best you buy fresh, firm and ruby-red stalks.

If you choose not to blanch the stalks, the process will take around 10 minutes. But if you do blanch them, it can take around 40 minutes.

If you are not familiar with blanching, this video will take you through the process step by step.

Start by washing the rhubarb and trimming the stalks. Cut them down so they fit into the container or bag you are going to use. If you are going to blanch them, do so now. Whether blanched or not, leave the rhubarb to completely dry out before proceeding.

Some people prefer to do a pre-freeze so that they are not all stuck together when it comes to using them. You can do this by arranging the pieces on a sheet of parchment paper in a single layer. Freeze the rhubarb for a couple of hours and then remove them from the freezer before packaging them.

Label the bags or containers you are going to use, store and put them in the freezer.

However, this doesn’t mean your life is at risk if you’ve eaten some rotten rhubarb, but don’t keep eating it.

If you experience symptoms such as severe stomach pains, dizziness or uncontrollable diarrhea, it is advised that you book an appointment with your healthcare provider.
