Creamy salsa verde

This sauce is an amazing combination of tangy, spicy, and creamy.  It goes very well with tacos or burritos.  I have substituted tomatillos for jarred jalapenos because I cannot get tomatillos in England.  But feel free to use either or a combination of the two!

Ingredients

1/2 c jarred jalapenos, chopped
4 cloves garlic, minced
1 cup cilantro, chopped
1 T oil
3 T creme fraiche
1 T mayonnaise
1 fresh chili, de-seeded and chopped
1-2 T fresh lime juice

Instructions

1) Using a hand-blender, combine and blend jalapenos, garlic, and chili in a medium bowl.
2) Add creme fraiche and mayonaisse, and combine further.  The texture should be smooth, and the hand-blender should get rid of any chunks of garlic or jalapeno.
3) Add the cilantro and blend briefly, to retain some of the texture of the cilantro.
