I just love the idea of going all scientific about cooking. That’s why I did a comparative table of Chinese cheese a few months ago, and why I tried making mapo tofu without boiling the tofu first. I don’t really know why; I just think it’s kind of cool. Like, cool to do comparative cooking experiments with vegan ingredients. This is the kind of reason I never used to get Valentines cards at school.
So, my very good friends at Mungo’s Hifi Sound System have been doing a night called Dub and Grub in Glasgow for the past seven years. They take over a pub venue, play dub music, and cook a set meal for super cheap (£8 for three courses). And it’s completely vegan: partly because of the dub reggae / Rastafarian / vegan connection, but mainly because they play in a vegan pub (The 78, which was recently listed in the top ten veggie restaurants in the country).
Now we’ve moved to Glasgow, I’ve been helping out with Dub and Grub, and last week got to design a menu. You have to be prepared to make 100 mains, maybe 30 starters, and 30 desserts. Cooking for that many people means your mistakes get amplified, so you need to be sure you’ve got the recipe right. So, the day before, cue cool experiments!
For the starter, I wanted to do vegetable tempura. I’d been amazed when we went to Japan by how easy it was to make. Our friend Seiko made a batter which contained only flour and water, and said the most important thing was to keep the batter cold (which she did by floating ice cubes in it). But other recipes variously call for baking soda, beer, soda water, and corn flour.
Because I’ve got more experiments to write about, I’ll skip the tables and jump to the conclusion. It does matter about the temperature of the water; if you have a warm batter, the tempura tastes a little burned. Corn flour doesn’t make a noticeable difference, but fizzy stuff does: still-fizzing beer and/or a small spoon of baking soda both make bubbles in the batter as it fries, making it lighter and crispier. The one on the left is with water, the one on the right is with beer.

The next experiment was the curry. For years we have been making a Japanese curry taught us by Taka, a fellow student when Kim was at university. It’s astonishingly tasty for something so simple. Simply fry up roughly chopped onion (maybe letting it brown a little); add equal amounts of potato and carrot in large chunks; nearly cover them in water with a few good dashes of soy sauce; add a drop of sesame oil and sugar to taste. Boil until slightly mushy.
Then, in Hong Kong (of all places), we had an amazing home-style Japanese curry which was richer and spicier than Taka’s curry. Trying to recreate it when we got home, I found that the secret ingredient is S&B Golden Curry Sauce. Roughly chopped onion, carrot and potato, in water, with an S&B curry cube dissolved in it. Super simple, and apparently what everyone in Japan does – even, apparently, chefs. But it resembles cheating, and what’s more, S&B curry cubes are 50p per person; a silly amount to spend when you’re mass catering on a budget.
So, my next experiment was a three-way face-off between Taka’s curry, an S&B curry, and my own attempt to recreate that elusive S&B flavour using only my wits and an internet search engine for inspiration. Here’s the showdown in action:

I was pleased that my own curry worked. I also trialed frying breaded slabs of aubergine to replace the breaded pork that would traditionally be served with curry in Japan. I did actually prefer, slightly, the S&B version, and it is super-simple (Vegan Lunch Box blogged the cube method recently). But I had used a packet curry powder, and decided that I could do better with my own spices and some inspiration from Justhungry.
Making it all for Dub & Grub on the day was an adrenaline rollercoaster. My recipe included a whole load of apples and bananas to provide the sweetness (instead of sugar), and for a while it was touch and go if it would taste like a weird, sickly stew; but it all came together in the end. We prepared as much as possible in advance, such as this vast stack of breaded aubergine slices:

In the event, it rained slabs of icy water for a couple of hours before Dub & Grub, so the place was pretty quiet; we only sold about 50 covers, which was disappointing. On the other hand, we got a whole load of enthusiastic feedback, with superlatives and happy faces filtering through the serving hatch. So I was really happy, and would love to do it again. So, if you have any suggestions for future Dub and Grub meals (3 courses, tasty, doable in quantity, on a budget), I would love your inspiration.
Here’s the recipe:
Japanese Katsu Curry (serves 100)
For the stew:
- 15 large cooking apples, peeled and cut into chunks
- 10 large bananas, peeled and cut into chunks
- 5 litres of weak stock
- 25 large onions
- 40 medium potatos
- 40 medium carrots
- 1 bottle brown sauce
- 350ml light soy sauce
- 3 cups of potato starch
- 4 tablespoons ground turmeric
- 4 tablespoons ground coriander
- 2.5 tablespoons ground cumin
- 2 tsp ground cardamon
- 1 tsp ground black pepper
- 1 tsp chilli powder
- 1/2 tsp ground cloves
- 1/2 tsp ground fennel
For the breaded aubergines:
- 25 aubergines, cut into 1/2” slices crossways
- 150g plain white flour
- salt to taste
- 6 x 250g bags of Japanese Panko (breadcrumbs)
To prepare:
- Boil the apples and bananas in the stock until mushy
- Blend them together with the brown sauce, soy sauce, potato starch, spices. Add more sugar to taste if necessary (this is supposed to be a salty/sweet curry).
- In a separate pan, fry the onion, then get the potato and carrot sweating
- Add the curry sauce and continue to cook until the veg are soft
- Make a batter by whisking water into the flour and salt until it’s just runny
- Dip aubergine slices in the batter and then into breadcrumbs; press the breadcrumbs onto the slices
- Deep fry the slices until golden brown
- Serve with Japanese rice, with plenty of curry sauce all over both the rice and the aubergine slices

The bottom of the curry pan was satisfyingly encrusted after a few hours of keeping the curry hot:
