I grow food for eating and am always telling newbies on our allotments that you do not have to have the biggest to have the best for food.
Seems that growers and cookers are two different species.
The guy who took home. Proudly, 15 huge marrows was disappointed when his wife was not delighted with what he brought to her kitchen for cooking.
You have to decide what you want when you grow veg. Is it for eating or showing off with?
You have no idea how many people told me that they hate stringy runner beans until I showed them the size they should be for eating. TAKE off and compost those which are too big so that new tasty ones can grow.
Cabbages, harvest a few too soon, and treat them as 'spring greens' instead of waiting for there to be tons hearted up and too many to eat.
Learn to cook or consult some one who can before you try to grow PLEASE.
