Harvesting, Cooking, And Then Eating A Dahlia Tuber

Hello friends,

Yes, I finally did it. I finally had the opportunity to try harvesting, cooking, and then eating one of my dahlia tubers.

I've been growing dahlias from seed this year as part of my dahlia breeding program, and a lot of the dahlias that flower just don't have the characteristics I'm looking for in a great seedling. Either they're single dahlias, or they have very plain and boring colours, or their flower heads are weak (and they droop), so I pull them out of the ground once I'm sure I know what sort of dahlia they are like.

I plant my dahlia seedlings very close together for spacing reasons, and when I decide that a dahlia is not what I'm looking for, that's when the dahlia seedling is pulled out of the ground, giving more space for other dahlia seedlings to grow in the garden bed.

All ornamental dahlias are edible, particularly the tubers, and their taste apparently is reminiscent of a potato crossed with celery, depending on which dahlia variety you harvest and cook. Dahlia tubers contain inulin (a prebiotic carbohydrate), other carbohydrates, have four times the amount of potassium than bananas have, and are high in fiber, making them a great food source if needed (Dahlia nutrition information (Nsabimana and Bo Jiang 2011).

With all this in mind, the next time I had to remove an unwanted dahlia seedling, I decided it was the time to try cooking and then eating a dahlia myself. The seedling dahlia donating its tubers was Dahlia SR 11, a boring single apricot dahlia variety that had flowered a few times, but its flower hadn't improved at all...

I dug the dahlia out of the ground, removed the stems and leaves, and then washed out as much dirt as possible from the tubers and roots. After bringing the root system of the dahlia into our kitchen, I cut off the small tubers the dahlia seedling had begun to grow. Small dahlia tubers we thought would be less fibrous, and more easy to cook with, compared to older and bigger tubers.

After giving the tubers another wash to remove all the dirt, I peeled the dahlia tubers as was suggested on the internet by other sources. With them now clean, I put the tubers into a small pot containing water, and added a bit of salt (similar to when boiling potatoes).

We brought the pot of water up to a boil, and let the dahlia tubers simmer for 10 minutes. At that point we tested the tubers with a knife and found them to be al dente, which was what my research suggested meant that the dahlia tubers were ready for eating. We cut one of the dahlia tubers up into thin slices and ate the slice plain...

The dahlia tuber was okay to eat, and did indeed taste like a potato crossed with celery (and it was a little earthy tasting too, a bit like beetroot). A bit plain, but okay. We sprinkled a little salt on top of the dahlia tuber slices, and it definitely improved the taste.

Wanting to explore eating the dahlia tubers further, we decided to pan fry the rest of the cooked and sliced tubers, to try out other flavor combinations with them, using ingredients we already had in the kitchen...

Here are the dahlia tuber flavor combinations we tried:

  • Chilli and Garlic - Definitely more tasty than plain, the flavor was improved by sprinkling a tiny bit of salt on top to finish.
  • Parmesan and Salt - Super tasty when fried plain and then sprinkled with parmesan and salt at the end.
  • Basil and Olive Oil and Salt - Quite pleasant, but not as nice as the Parmesan and Salt.
  • Fried in Butter with Chilli and Lemon Juice and Garlic - Definitely my favorite. The chilli and lemon and garlic combination made the dahlia tuber super tasty. We think it would've been better with lime juice instead of lemon, but we didn't have any available at the time.

With all those flavor combinations completed, we were out of dahlia tubers to eat, and that was perfectly okay for ending our experiment in dahlia cooking and eating.

I think that doing this experiment in dahlia cooking and eating was a good experience to try once. It was okay to eat, but if it came to a choice between eating potatoes and eating dahlia tubers, potatoes would be my choice every single time. If it ever came to a point that there was no choice but to eat dahlia tubers to survive (like during a zombie apocalypse), I would very happily do it, as long as I didn't need to eat any of my precious named dahlia varieties to do so. Those are sacrosanct, but they would make great seed producing dahlias, and those seeds could then go onto produce seedling dahlias tubers which I would happily to eat in the long term...

Have a wonderful day
