another option all together is to use some cream to thin out cream cheese and then use the cream cheese with the yolks. the flavor is different, but we like it...especially the raw cream cheese and raw cream from a nearby farm
we like them plain or the addition of smoked salmon bits, capers, and maybe onion are a delicious combo with the faint cream cheese flavor
I've mixed the yolks with raw cream (even just the cream from the top of gallon of milk), a pinch of sea salt, curry powder & a dab of chili paste. Pretty tasty. I sprinkle a dusting of curry powder over top for looks.
