You're welcome Amy,

Actually you can find Jewish food in Singapore. There is a kosher grocery store attached to the main synagogue (there are two of them for some reason, but as we say in France, "two jews, three synagogues").
Moreover, as there are many western expats living here, you can find Australian and American brands in major supermarkets.
The community here is mostly bagdadi jews, that is jews from Iraq who then lived in India and are now all across SE Asia. Most of them have lived in the region sinced the 19th century or beginning of the 20th (Sassoon, Kadoorie...are famous bagdadi jews).
But the community is small to French standards, and even smaller to New York standards...
