Growers forcing the issue

Bell-shaped terracotta pots are used to ‘force’ rhubarb in the kitchen garden at Rudding Park Hotel’s Michelin-starred restaurant ‘Fifty Two’.

I’ve been lucky to have another short trip away, this time to the swanky Rudding Park Hotel near Harrogate for a spa break with my best friend. We started doing this in 2021 when we realised we had been friends for 50 years. We felt that was something worth celebrating, and ever since have made sure just the two of us get away once a year for a weekend of pampering somewhere nice.

We had an afternoon in the spa followed by some relaxing treatments and ended up with a delicious meal in the restaurant. It is a very impressive place, and the staff are clearly well trained, doing everything to make sure your stay is as trouble free and relaxing as possible.

The next morning we were not in any hurry to leave, and decided to have a potter about the grounds. This time of year is hands down my favourite, and we admired the magnificent horse chestnut trees swathed in blossom candles and the rhododendron and azalea shrubs resplendent in their floral frocks of pink, orange, yellow and purple.

There was also a kitchen garden where they grow a huge variety of produce to supply the Michelin-starred restaurant, Fifty Two, which sits just next door. Guests are welcome to wander round and jealously marvel at how healthy and robust the 500 varieties of fruit, veg and herbs look. I’m impressed by people who can grow things. I manage to kill every green specimen that crosses my path, even the herbs that you get from the supermarket. As soon as I put a pot of coriander on my kitchen windowsill, it keels over and dies.

We were intrigued by some strange elongated bell-shaped terracotta pots dotted about the growing beds, and discussed what we thought they might be. In the end we asked one of the gardeners who was busy weeding. Turns out we were speaking to head gardener Emma Pugh, who is extremely knowledgeable about all things horticultural and she explained it was for forcing rhubarb. I’ve heard of ‘forced’ rhubarb and know that in Yorkshire we have the famous Rhubarb Triangle where commercial growers produce rhubarb in huge sheds that do not let in the sunlight. However, I hadn’t before stopped to think about why they might do that.

Emma explained that by restricting the light, the rhubarb is ‘forced’ to grow quicker in a quest to find the sun, and this produces a much sweeter, flavoursome variety than those left to grow au naturel. The stems are longer and thinner, and less stringy too. The lack of sun also means it has a bright pink stalk as opposed to the more bitter red-green ones we associate with the rhubarb from our back gardens. The dark environment also means rhubarb leaves are yellow rather than green.

The terracotta domes were replicating the forced atmosphere so that the chef can create prettier, sweeter and tastier desserts for his diners. The pots are placed over the rhubarb ‘crowns’ in January, and the plant behaves as if it is still underground, forever reaching up towards the daylight. However, a rhubarb plant should only be forced for one season before it is rested, as it really takes it out of the plant having to put so much effort into trying to find something it never will. So the pots are moved around, with the same plant only being forced once every few years.

Emma also explained that the chef had asked her to experiment with forcing other vegetables to see if it improved their taste too. Other commonly forced vegetables include chicory, sea kale and asparagus, and the technique was popularised by the Victorians who wanted to grow produce out of season. Forcing does not just refer to the lack of light, but also to creating warmer temperatures, such as in greenhouses, to encourage plants to grow more quickly, or out of their normal growing period. And it’s worth remembering, for your next pub quiz, that rhubarb is not a fruit, but a vegetable due to its lack of seeds. 

Do you remember a while back I tried ‘wilting’ dandelion leaves in the way you would cook spinach, after reading a column my dad had written suggesting it? It was awful, chewy and bitter.

I wonder if forced dandelion leaves would taste better?
