Cream the shortening, water & sugar together until light & fluffy. Add the molasses & egg yolk & mix until well blended.
In a separate bowl, whisk together all the dry ingredients. Gradually add the dry ingredients to the wet mixture. If using a stand mixer, use stir. The dough will be sticky.
DO NOT ADD MORE FLOUR REGARDLESS OF HOW TEMPTED YOU MAY BE!!! Too much flour will make the cookies tough. Form into 2 flat disks & put in the freezer for at least an hour or more.
Preheat oven to 350°F.
When the dough is cold enough to handle, roll it to about ¼” thick between 2 pieces of wax paper (the wax paper keeps you from having to use more flour). I roll mine a little thinner because I like a little crispness on the edges.
Gently press together the scraps into another disk & put back in the freezer until ready for use. Bake for 8-10 minutes on parchment lined cookie sheets. Cool on pan for about 5 minutes before transferring to a cooling rack. Cool completely before decorating.
Chef’s Note: I use shortening instead of butter or margarine because shortening is flavorless and doesn’t impact the spices. I think butter is best served in sugar cookies. If you decide to substitute butter or margarine for the shortening, omit the water from the recipe.
Combine soy, rice wine, brown sugar & ginger in a small bowl & mix to combine.
Add fish to bowl & allow to marinate for about an hour.
Lay out a large length of aluminum foil on the bench (you can use two sheets of the same length to make is stronger).
Rip apart the coriander & lay into the center of the foil. Layer the lime & fresh lemon slices over the top of the coriander. Lay the marinated fish into the center of the coriander/lemon/lime bed. Sprinkle with salt & pepper.
Layer another sheet of foil over the top of the fish & fold in all sides of the foil tightly to make a fully air tight parcel.
Place on a cookie sheet & bake in the oven for 15 minutes. When you open the foil the fish should have changed color & be firm to the touch.
