The 9th of February is a day for bagels, cream cheese and cured salmon slices, otherwise often reserved for Sundays only.
The bagel you use needs to be a good old-fashioned plain-flavour bagel: sesame or poppy seeds on top are fine, but a blueberry or pizza flavoured or cinnamon and raisin bagel just wouldn’t cut it for this dish. A Jew would go to hell for even thinking of it.
Any cream cheese should be plain as well (sundried-tomato or apricot cream cheese are definitely out.)
Up until recently, you couldn’t get bagels and lox in Israel.
