Sachiko Seth brings his creativity to the kitchen, much like the 23 tattoos he proudly wears. But don’t let the edgy exterior fool you; he is a softie often springing surprises like the pork-stuffed char siu buns coming hot off the oven at Boma Asian Bakery. The bakery by Sachiko and his friend Manisha, which opened on Middleton Row in 2021 amidst the pandemic wave, serves up sweet and savoury temptations, with a side of Korean pop culture. “I believe in simplicity with a twist,” says the Kalimpong-born chef. I quite believe that because I’ve never seen Sachiko thriving on networking and socialising. In fact, his culinary creations at The Blue Poppy Thakali and Boma speak volumes without the need for small talk. He shares three recipes with us from the Boma kitchen.

Choux Pastry


  • Butter: 115 grams
  • Sugar: 5 grams
  • Milk: 100 grams
  • Water: 100 grams

  • Take butter, sugar, milk, and water in a saucepan. Heat and let it come to a boil.
  • Switch off the heat and mix in the flour vigorously.
  • Take the dough out in a bowl and whisk in the eggs one by one.
  • Add vanilla essence and whisk some more. The batter should be thick with no lumps.
  • Pipe it onto a baking tray lined with parchment or a baking sheet.
  • Bake for 20 minutes at 190°C.
  • Let the baked choux cool down and fill with your preferred filling like cream or custard.

  • Add the egg.
  • Add in the milk mixture little by little and knead into a dough.
  • Lastly, add the butter and knead into a soft dough.
  • Oil the insides of a big bowl and place the dough in it. Cover with wrapping plastic or a clean cloth and let the dough rise for about an hour and a half.
  • When the dough rises to double its size, knead again and flatten out with a rolling pin until half an inch thick.
  • Cut out donuts with a circular cutter or lid and place them on a floured tray.
  • Let them rise again for 20 minutes to half an hour.
  • Fry them in medium hot oil until golden brown.
