When you have as many food allergies as I do (I've got 15-20 food allergies), you need a book like The Food Substitutions Bible: More Than 6,500 Substitutions for Ingredients, Equipment and Techniques to help you figure out what you can eat. This is a book I keep in my kitchen for easy access. You can easily find substitutions for things like:
- applesauce (pumpkin or plum puree)
- carrot (parsnips, daikon, turnips, or celery)
- lemon juice (brewed lemon tea, lime juice, or white wine vinegar)
- pastry bag (plastic resealable bag or rolled parchment paper).
Whether you are looking to substitute a key ingredient or utensil, create a different flavor or texture, or look for a healthier option, you will find a wealth of information and ideas that will give you the confidence you'll need to improvise!
