There are no fixed rules, and that's the beauty of cooking. My favourite drink is called Capirina. It's made by mixing Absolut Vodka, Ginger Ale, and squeezing two green limes over it, plus ice, of course. Stout itself has chocolate in it, which gives the drink the dark colour. At Brewerkz, we use about 1kg for 2000 litres of stout - that's not too much.
Beer is a lot about taste, and it depends on each person's preference.
Overall, because beer is so refreshing, it goes very well with spicy food. Otherwise, I will go to Marche, or Esmirada. I also go to Geylang for the 24-hour soybean stall. If you don't like to be in the kitchen, don't be there. Buy food - don't make it.
