Cauliflower is a sensitive plant, and when the growing heads reach around two or three inches in diameter, sun exposure becomes an issue. 

Think of the bitter taste like sunburn and the ultraviolet rays torched the plant; along with these outdoor issues, not harvesting these plants before reaching the six inches diameter can also leave a bitter aftertaste.

Just like when overcooked in the sun, doing so in the pan can be just as much of a cause for the bitter taste that would require a chef’s trick or two to remove from a dish or plate. 

Is this Common?

One way to look at it will be how difficult it is to cook these veggies because, unlike its similar-looking cousin, the broccoli, it does not change coloring throughout the cooking process. 

Making it relatively easier to overcook these plants, in combination with the ease with which the plant heads burn in the sun, equates to this being a common occurrence. 

There will be easy ways for a gardener or farmer to protect their cauliflower from the sun, and there are just as simple tips for cooking this veggie without losing the integrity of the cauliflower. 


Does it mean Your Cauliflower is Rotten?

The taste does not necessarily come from rotting but rather from leaving them in the ground for too long, as discussed earlier in the article. 

If you do not harvest the cauliflower before it reaches the six inches diameter mark, it will develop notes of bitter flavoring and is better fed to the livestock, for not many will eat it. 

To help a novice gardener or beginner farmer to identify the signs of the spoiling of the cauliflower veggie plant will be:


  • Discoloration or widespread spottiness
  • Soft spots or mushiness, accompanied by an unpleasant odor.
  • Spreading or separating florets, with the leaves wilting


What Can Cause This?

To recap, some of the conditions that cause a cauliflower plant to become bitter will be overexposure to sunlight, allowing for overgrowth of the plant head, and cooking it in a skillet. 

As for other reasons, we will have to think about certain circumstances which can make the cauliflower overheat, or in some cases because of underwatering.

As drought conditions continue to worsen and migrate about the United States, crops like cauliflower are going to be under additional risks of overheating, which is a possible cause for the bitterness found in the veggie at dinner time. 


How can You Fix it?

Have no fear. The emergency chef’s wisdom is here, meaning there will be some simple ways to remove or work around the bitterness of the cauliflower which has been caught in this situation. 

One well-known and popularly used kitchen trick is adding fats to the dishes; these lipids will be able to neutralize the bitterness in more than just cauliflower, but out of most ingredients naturally. 

The next move would be adding spices and seasonings, such as a sprinkle of salt, a pinch of baking powder, or a sweetness from sugar or fruits (for example). 


How Can You Prevent it from Happening?

There are going to be steps a gardener can take, along with the chef in the kitchen, to avoid bitterness in the crops being grown. 

For starters, when the cauliflower head reaches around three to four inches in diameter, it will be time to harvest.

As far as protecting these heads from the sun, when they reach about two inches in diameter, expert farmers will use the broadleaves as a bonnet to shield the cauliflower from the sun. 

The chefs will have to focus on keeping the cooking to a minimum. Cauliflower does not require much cooking but requires attention to detail. 

For instance, broccoli will have a certain glow when being cooked, while cauliflower will need a chef to test it using a fork or poke. 


Final Thoughts on Why does Your Cauliflower Soup Taste Bitter

Now that we have covered the ease with which cauliflower can become bitter, there will be many positive benefits from eating this veggie. These little veggies are packed with nutrients, especially the coveted fiber, to cover daily needs and antioxidants. 

Not every kid will like broccoli, even when covered in melted cheese. Same case when it comes to cauliflower; if you can get past this, the benefits of consuming these veggies will certainly outweigh the risks of bitterness.
