The taste of this chicken hotdog, while better than commercial products, is not one I like. I have always preferred turkey products to chicken.
If you like chicken hotdogs the fat replacement works well but I would recommend adding it after emulsifying the meat, mixed with water to eliminate the whipped air pocket soft texture. Click on picture to see the texture up close.

Chicken Hot dogs
5 lbs. meat from chicken legs and thighs
1/2 lbs. chicken fat and skin
1 tsp Cure #1
2-1/4 tsp salt (not iodized)
3/4 Tbs white pepper
2 tsp mace
1 tsp paprika
1 1/2 cloves of garlic (crushed)
5 tsp Fat replacement
1/4 cup ice water
Grind the skin and fat (nearly frozen) through the small 1/8" plate. Refreeze the mixture and run it through the grinder once again. Grind the poultry meat through a 3/8" plate. Alternately, you may wish to use a food processor to emulsify the meat, fat, and skin. Combine the mixture with the remaining ingredients and develop the primary bind. Stuff 32 mm hog casings into a "rope" or twist links in the length of your choice. Smoke the links using thin smoke inside a preheated 120° F. smokehouse, raising the temperature only a few degrees every twenty minutes for the period of 3 hours. Finish the cooking process by poaching the sausages in water heated to 175° until the internal meat temperature reaches 155°F. Immediately place the sausages in ice water for a few minutes. Be sure to keep the sausages refrigerated.
