I came across this recipe while looking for interesting things to do with blue cornmeal. Athough this is time consuming I think it looks interesting and fun to make. Recipe source: Bon Appetit (December 1987)
To make the fettuccine: mix the all purpose flour (1 cup plus 1 1/2 tablespoons), blue cornmeal, semolina, salt , cumin and cayenne in a large bowl. Make a well in the center of the ingredients and add eggs, and blend together with a fork, until all the flour is incorporated. Knead douh on a lightly floured board until smooth (4-6 minutes), kneading in additional flour if sticky. Wrap dough in plastic wrap and let rest 30 minutes.
Cut dough into six pieces. Working with one piece at a time (keeping the rest covered), fold piece into thirds. Using a pasta machine at it's widest setting, run dough through several times until dough is smooth and velvety, flolding dough before each run and dusting with flour if sticky. Repeat narrowing rollers after each run until pasta is 1/16th inch thich, dusting with flour if necesary. Hang dough sheet on drying rack or place on kitchen rack to dry. Repeat with remaining pieces of dough until all is completed. Set aside until dough sheets look leathery and edges begin to curl (10-30 minutes). ***Pasta must be cut at this point or it will be too brittle to work with.***.
Run dough sheets through the fettuccine blades of pasta machine (or cut by hand into 1/4-inch wide strips). Arrange pasta on towel.
To make sauce: boil cream in a large saucepan until reduced to 1 1/3 cups. Cook chorizo and jalapeno in a large skillet over medium heat until brown, crumbling the chroizo with a fork (10 minutes). Stir in cream, cilantro and cayenne and season with salt.
In a large pot, add pasta to a large amount of rapidly boiling water, stirring to prevent sticking. Cook until tender (4-5 minutes). Drain. Add pasta to cream sauce and toss to heat through.
