While I have not been able to find a commercially made mayonnaise that is free from soy, Brianna's and Organicville make several varieties of creamy salad dressings that are egg, dairy, and soy-free. These can be used to substitute mayonnaise in chicken or pasta salads. Just mix equal parts salad dressing and plain soy-free yogurt such as those made from coconut or rice milk. This helps make a thicker dressing. So, if a recipe calls for 1/2 cup of mayonnaise, mix together 1/4 cup each of salad dressing and yogurt.
There are five varieties of egg-free mayonnaise: Original, Grapeseed Oil, Reduced fat, High Omega-3, and Organic. All contain soy ingredients. Original Vegenaise tastes like traditional mayonnaise. I found that the Grapeseed Oil variety had a taste that resembled Miracle Whip. These products are available at Wegmans and Wholefoods Market. I have, on occasion, found it at Blooms. You may also purchase their products from the Follow Your Heart on-line store.
Nayonaise comes in three flavors, original, dijon, and fat-ree original. It is vegan, egg-free and gluten-free. However, the main ingredient is soymilk. The taste and texture is similar to regular mayonnaise. Giant Food and Bloom are two grocery stores that carry this brand. Look for it in the refrigerated section of the produce aisle.
Their Light Canola Mayo is made with organic ingredients. It is vegan, egg-free, and gluten-free. However, it contains soy. The mayo is available in jar, or squeeze bottles. Gian Food and Wegman's carries Spectrum organic mayonnaise. However, they do not always stock the Light Canola Mayo.
Brianna's makes gourmet flavored salad dressings. Not all are allergen-free. Poppy Seed, Blush Wine Vinaigrette, Lively Lemmon Terragon, Zesty French, Real French Vinaigrette, The New American, and Champagne Caper Vinaigrette are among the flavors that do not contain the nine most common allergens; including soy. The flavor of the Poppy Seed Dressing is slightly sweet and is great in chicken and fruit salads. Brianna's can be found in most grocery stores. I have been able to find it at Harris Teeter, Safeway, Giant Food, Bloom's, and Wegmans.
Manufactures a wide variety of products that are organic, vegan, gluten free, and dairy free. These include salad dressings, mayonnaise, and cole slaw dressing. Not all products are soy free. The salad dressing flavors include caesar, ranch, and thousand island. I have been able to find different varieties of the salad dressings in most grocery stores such as Harris Teeter, Giant, Safeway, Wegmans, and Wholefoods. I have not tried the mayonnaise because it is difficult to find in stores.
