The whole point about cucumber sandwiches is that, unless done really well, they’re as dull as the sum of their ingredients. They glory in their own delicacy: rumor suggests the nutritional redundancy of a thin, white bread sandwich filled with a fruit that’s 96% water was intended to celebrate the sedentary lifestyles of the Victorian upper crust. Certainly they’re not going to sustain anyone through a hot afternoon at the plough, but it’s this very insubstantiality that attracts me – they’re perfect for afternoon tea, because, unlike a ham or a cheese variety, they won’t spoil your appetite for dinner.
Should you need any further persuading of the merits of this excellent dish, the cucumber sandwich was last year lauded by American scientists as the best thing to eat to regulate body temperature and stave off dehydration during a heatwave. Admittedly, their formulation recommends wholemeal bread, crusts left intact, and spread with mayonnaise, but hey, what do they know? They’re American.
The cucumber
Peeling is mandatory, presumably in case some pesky fiber creeps into this most refined of meals. Although sogginess is fatal in a cucumber sandwich, I find I rather miss these liquid centers – the sandwich seems almost dry without them. If, for some reason, you have to make them in advance, however, seeding would be wise.
Lemon juice would probably work better, but after salting the cucumber, as some chefs practice, I don’t think it’s necessary. The salt draws out some of the liquid from the cucumber, leaving it firmer and less prone to sliminess, while also bringing out the flavor – 20 minutes is quite sufficient, though.
The bread
A soft white, the softer the better, seems to be the order of the day – this is definitely not the place for chewy sourdough or wholesome whole meal. It should almost melt in your mouth once you cut the crusts off, but not quite: I’m not one of those people who think that there’s any place for cheap white sliced of the type often fondly known as “plastic bread“. Real bread also comes in the soft white variety, and worked a treat in most of the sandwiches I tried.
The butter
You could use mayonnaise instead, there doesn’t seem much point: butter and cucumbers are a winning combination. As any experienced sandwich maker will know, it also acts as a handy seal between filling and crumb, protecting the latter from any dampness that threatens to make it soggy.
Some Chefs beat theirs with creme fraiche and chopped egg to make a more substantial layer: delicious, but it makes the cucumber an also-ran.Meanwhile, some dab it altogether in favour of cream cheese, which makes his more a cheese sandwich with added cucumber.
Other Chefs use salted butter, but most other people specify unsalted, with good reason. I rarely buy it otherwise, but this is one place where its creamy sweetness comes into its own in contrast to the salty, refreshing slices of cucumber.
Seasoning
No further salt required, obviously, after treating the cucumber, but pepper is very welcome. White pepper, is preferable here: it delivers the same spicy hit as black pepper, but without the accompanying aromatics, which compete with the cucumber for flavour.
Extras
Chop mint in sandwiches, which seems to be a popular choice in the States. It is an excellent partner for cucumber – I’d say together they sum up the taste of a British summer – but again, too dominant here.
I won’t weigh into the quarters v triangles v fingers debate, except to say that fingers, the most time-consuming and dainty of the lot, are to my mind the most suitable here. I will urge you to press the sandwiches down firmly as you cut: it will make them neater. And where a cucumber sandwich is concerned, neatness is really rather important.
The perfect cucumber sandwiches
(Makes 9)
1/2 cucumber, peeled
Salt
6 thin slices of good white bread
Unsalted butter, at room temperature
White pepper
Cut the cucumber into slices as thin as you can make them, and put in a colander or sieve. Sprinkle lightly with salt (don’t go overboard) and leave for 20 minutes. Taste to check you haven’t oversalted them: you can rinse them at this point if so.
Lay out a few pieces of kitchen paper on the work surface, place the cucumber slices on them, and pat dry with more paper.
Lay out the bread and butter each slice generously. Arrange the cucumber on half the slices, overlapping each round, and sprinkle with ground white pepper. Top with the remaining slices.
Pressing down firmly, cut the crusts off, and then cut into neat fingers, triangles or quarters of roughly equal sizes. Serve immediately, with good tea.
Cucumber sandwiches: are you a fan, or are they a silly Victorian affectation that deserves to go the way of the top hat and the whalebone corset? And if not, what do you like to do with this most refreshing of summer crops?
