Housemates and best friends Henry Firth and Ian Theasby are the masterminds behind the wildly successful vegan platform BOSH!

Their plant-based recipes go viral as standard, their videos professing the magic of vegan ramen, meat-free burgers, and quitting steak. And they're very convincing. This month, they also celebrate the release of their new book, BOSH! How to Live Vegan: Simple tips and plant-based hacks. We grilled them on all the delicious stuff that gets their taste buds going - or not, as the case may be...

Your death row meal would be...

Theasby: The biggest juiciest ripest mango the world has ever seen, just on its own, because if you think about food as a gift from above, and you've got the best mango in the whole world, that'll do.

Firth: Fish and chips and loads of tartare sauce - but obviously vegan.

The thing you still can't make is...

T: Steak! Ha. You can cook anything if you put your mind to it.

F: [Vegan] Yorkshire puddings.

Your favourite store-cupboard essential has to be...

T: Garlic, onions, salt.

F: Chilli flakes, nutritional yeast.

The kitchen utensil you couldn't live without is...

T: Wooden spoon.

F: Tongs, it's all about tongs, they're an extension of your hand.

If you get hungry late at night, the snack you'll reach for is...

T: A Beyond burger.

F: Miso soup if I'm feeling healthy, coco yoghurt granola if I'm fancying something a bit more substantial.

Your signature dish is...

T: We both have a dish in this book.

F: I'll go for the one with my name on - the biryani, the banging jackfruit biryani - it's so good.

T: I'll say mine, Ian's delightful dal.

F: Two great dishes that'll go really well together.

You like your eggs...

T: Scrambled, but you use a blend of silken tofu and firm tofu, and use black salt to flavour it, and a bit of turmeric to colour it.

F: Nuevos ranchos - or non-existant, I never liked eggs, something about the taste and sulphuric smell never worked for me.

Your favourite childhood dinner was...

T: Sunday roast at my grandma's house.

F: Vegetable lasagne.

If you're ordering takeout, it has to be...

F: Massive curry, lots of poppadoms, pickles, mango chutney, and about four different dishes.

T: We live together, so I'd probably say the same.

Your ultimate hangover cure is...

T: Teetotalism - haha. No, lots and lots of water, a bit of exercise the next day.

F: Barbecue Pringles, sweets and watching Interstellar again and again and again on a loop, probably will cry somewhere in the middle.

You cannot stomach...

T: There's a couple of things I'm not bothered about, Aperol spritz!

F: I'm really not down with negronis, I so hate that flavour.

Your dinner party staple has to be...

T: The meal I find myself cooking most for people, is brunch on a Saturday, scrambled eggs, but then I quite like making a pesto and a hummus and getting some really nice bread, then roasting off some vine cherry tomatoes.

F: It's gotta be that classic lasagne or the BOSH! mushroom wellington. Of our one billion [YouTube] views, a sizeable amount of them have been for the mushroom wellington, it's fed thousands of people.
