1, What is your favourite food?
Hard question, because for one I don't have all-round most-favourite and also because it changes with season. Currently - because it is summer - my most favourites are squash pancakes for breakfast (because they are fast to make, filling, and more healthy than ordinary pancakes) and freshly caught fried fish - common perch more precisely (father often goes fishing on weekends and brings them).
2, What is your favourite food preparation method?
Don't have one. Any way can be fun in right mood - from simply slicing a salad to spending couple of hours in kitchen making a complicated dish.
3, What is your favourite cuisine or style of cooking?
Russian, because that's what I grew up with. Other cuisines might be fun to try, but all too often it is hard to find right ingredients.
Plus, some dishes are good only in right climate. You won't be able appreciate thick borscht or shchi in hot weather, or okroshka or light salads in cold weather. Same goes for cuisines from other countries.
4, Do you have any dietary restrictions and if so what are they?
I have a couple of food allergies - mostly on annoying level, but I can't stand peanuts and cilantro (green part of coriander) is flat out dangerous for me.
Also, thanks to my Korean grandfather, I have low tolerance for some dairy products, I can eat them but not too much. Which is sad as I love milk.
5, If you could introduce the whole world to one ingredient to improve their culinary experience, what would that be and why?
Don't know. I don't use anything exotic really and really of all spices I only use salt, bay leafs and a mix of peppers.
