It's a little personal accomplishment to have a hopper recipe on this site. I never thought I would ever make them myself. They were my aunt's "thing" -- my parents left them to her to make and we enjoyed a generous batch whenever she did--perhaps that added to their mystique, somehow. But what mystyque? We're talking about the equivalent of a pancake batter, although these were often made special with the addition of eggs and they had a beautiful, covetable, lacy crust around the edges--and that, you see, was because of the special pan used, that allowed the batter to be swirled thin around the pan but evenutally pool in the centre and set to a thick, soft pillow there. A pillow that cradles a softly poached egg--the milkiest egg you've ever cooked. Ok, I see it now. These will always be a little magical to me, though no longer mysterious.
Let's talk about the batter, like the one you might make every weekend. This one uses rice flour and it sits covered overnight--that's how it differs from a typical pancake batter though it requires no more work. The batter ferments which is why hoppers have that slightly complex but subtle "bread-y" flavour and wonderful aroma that you get when you're so close to them you're tearing off a piece to eat, and that makes them ideal for savoury accompaniaments. The batter cooks in hopper pans--so small, lightweight and affordable that they would be worth adding to your already-packed kitchen (see my post about hopper pans) so that you can have hoppers every weekend or for dinner too. Did I mention the sides (*see below) can be made in batches and frozen? Meaning you could have hoppers within minutes if you took two minutes 8-12 hours earlier to stir a batter together.
The delicate crust that forms at the edges of hoppers are the reason to buy the pan. It's golden, it so thin it can shatter at the outermost tip but for the most part can handle a dip in warm, golden egg yolk and then be gently scooped through some sambol for a crispy, rich and spicy little boat that drips and threatens to break before making it to your mouth. The fluffy centre can be dragged through curries before being chewed, reminiscient of pancake but with much more flavour. And then...
...there's the egg. This is an egg unlike any you've had before. It's essentially poached, but not in water so the whites and yolks get to branch out more and retain more of their individual identities. Cooked only on the batter, the eggs retains even more of their integrity than when cooked in tomato sauce or on a pizza, undisturbed by competing elements, not encroached on phycially or by other flavours. In that sense it's like a fried egg that arrives solo and can be given proper attention, but it cooks much more gently, never coming in direct conact with heat, and the result is a warm golden centre but also the milkiest whites ever.
Both cooking hopper batter and adding an egg to the centre can be attempted in a regular, seasoned skillet but not to the same effect. What I would try is to swirl the batter, cook for a few seconds and then lift and swirl so that the uncooked batter keeps being sent to the edges where you will hopefully cook up a thinner and crisper intererior than the centre. Keeping the egg in the centre would be more of a challenge but a very small, high-sided pan might do the trick. Here's hoping you get to experience the same thing one way or another. If not, please don't hate me if I made you want one.
