Sorry I have, again, been slow. Short stories literally do not write themselves.
If you are going to fill a couple of marrows, first you must hollow out your marrows:
Cook some of those nice green lentils (puy, they are usually designated, but there are ones from Sainsbury's that aren't that are very nice). At the same time, bake the marrows until they soften. This takes about twenty minutes. I am sure you are interested to learn that this is the only context in which I have ever cooked marrows. Maybe they are delicious in other contexts. From this recipe, in which they are great as a lentil-vector, I doubt it.
Also, soften 4 onions, 4-5 cloves of garlic, no cloves, and then add 10-12 normal sized tomatoes. If you don't know what size is normal for a tomato you have no place in the kitchen.
Stir the resulting mess into the drained lentils along with a tubful of harissa the size they sell in local Sainsbury's, which looks like it must be a standard sort of size (with the tedious predictability of an unloved season your guests will describe this as 'too much harissa'), and then spoon the results, such as they are, into your marrows.
Bake for another 25-30 minutes until the top has just a little crunch and dust heavily with parmesan.
For pudding, may I suggest Czech fancies
are something to be avoided. In real life, they look much more disgusting than they do in this picture. Ukrainian chocolates,
on the other hand, aren't bad. And there is the ever popular caramel vodka (along with delicious amaretto biscuits).
Over for now.
