Gol gappe are the hardest thing on any street food menu to get right and the easiest to get wrong. They are also the cheapest, which is why most places treat them as a filler rather than the thing they should be judged on. Get them right and everything else on the menu is probably fine too.
Here is what actually separates good from bad. It is also what to look for when you are ordering them anywhere in Manchester.
First, the names
Same dish, different homes. In Pakistan and north India they are gol gappe. In Mumbai and much of western India they are pani puri. In Kolkata and the east they are puchka. In parts of the UK you will see golgappa on the menu with the spelling that suits the owner.
The differences are real but small. Puchka tends to be spicier with a heavier tamarind hit. Pani puri is often sweeter. Gol gappe sit in between and lean on the paani being sharp and cold. If you search for any of these in Manchester you are looking for the same thing.
The paani is the whole dish
This is the one thing to take away. The shells are just a vehicle. What makes gol gappe worth eating is the imli paani, the tamarind water you pour in at the last second.
A good paani is tamarind, mint, coriander, green chilli, black salt and cumin, blended and then left to sit so the flavours settle. It should be properly cold, sour first, salty second and hot at the back of the throat third. It should make you pull a face slightly.
Bottled concentrate tastes of vinegar and sugar and nothing else. You can tell within one bite. We make ours in house for exactly this reason. It is the thing we would want to be judged on.
The shells
Puri should be light, hollow and properly crisp. Pick one up and it should feel like almost nothing. If it bends rather than cracks it has been sat out or stored badly and the whole thing will go soggy before it reaches your mouth.
Almost nobody in the UK fries their own shells, including us. That is normal and not a mark against anywhere. What matters is how they are stored and how quickly they are used. A busy place turning over stock daily will always have better shells than a quiet one.
The filling
Spiced chickpeas, sometimes with potato. It should be seasoned on its own rather than relying on the paani to do the work. Taste a spoonful before you start if you get the chance. If it is bland, everything after it will be one note.
Chopped onion and coriander should be fresh that day. Pomegranate on top is not traditional everywhere but it earns its place, because you want something that pops against the crunch.
How to eat them
In one go. That is not showing off, it is the only way it works. The shell is designed to break in your mouth so you get crunch, filling, sour water and heat at the same time. Bite one in half and you get a wet mess and a dry crisp.
Eat them the moment they are filled. Thirty seconds is fine. Two minutes and the shell has gone soft and you have lost the point of it. This is also why gol gappe are a terrible takeaway and a brilliant thing to eat where you are parked.
Chaat bombs, if you want the same thing tidier
Same shells, but filled with chickpeas, chutneys, sweet yoghurt and pomegranate and finished with the paani. Less dramatic and much less likely to end up down your shirt. If you are eating in the car this is the sensible order.
If you want the full chaat experience, aaloo papri chaat gives you the crispy papri, the yoghurt and the chutneys in a bowl with a fork, which solves the same problem a different way.
Where to get them in Manchester
Rusholme and the Curry Mile is the obvious answer and there are good ones along Wilmslow Road. Longsight and Cheetham Hill both have places doing proper chaat. The catch is that most close relatively early and most mean parking up and queueing.
We serve gol gappe and chaat bombs at Lahori Lane on Redgate Lane in M12 until 2:00am, seven nights a week. It is a drive-in, so you park where the attendant points you, put your hazard lights on and a server comes to the car. The food is brought out to you, which for gol gappe specifically is the right way round: you can eat them where you are parked, within seconds of them being filled, instead of carrying them home and finding they have collapsed.
Longsight, Gorton, Ardwick, Levenshulme, Openshaw and the city centre are all a short drive. The full menu is here with prices.
The short version
Judge the paani, not the shell. It should be cold, sour and made on the premises. Eat them whole and eat them immediately. If a place gets gol gappe right, order the rest of their street food with confidence.
