Tips for purchasing authentic Andouille sausage include checking the ingredients and searching online, mail-order food retailers, such as Jacob's World Famous Andouille and the Cajun Grocer. Cook's Illustrated found Jacob's World Famous Andouille to be the top in texture, flavor and heat.
Traditional Andouille sausage features ground pork, salt, garlic and seasoned black pepper as the primary ingredients. It's then smoked over pecan wood and sugarcane for 14 hours. Jacob's World Famous Andouille has been making the sausage for over 85 years, and this company uses cubed, lean pork rather than ground pork. Jacob's Andouille is available online for around $9 per pound, as of 2015. Jacob's also adds red pepper and allows the sausage to hang in a cooler overnight to cure.
Other top Andouille retailers include Wellshire Andouille Sausage, sold at Whole Foods for about $7 per pound, Chef Paul Prudhomme's Hot Andouille and Bruce Aidells Cajun Style Andouille Sausage, according to Cooks Illustrated. Each sausage comes in at under $10 per pound and can be purchased online.
The Cajun Grocer has a variety of Andouille sausages available to order online, from venison and pork smoked Andouille to a smoked alligator and pork sausage. Sold in quantities of 1 pound to 5 pounds, the Cajun Grocer also gives discounts to larger purchases.
