I'm trying to work out the optimal ordering of condiments on a burger. Here I took a clue from "Meathead Goldwyn" in his Huffington Post article The Zen of Burger Condiments. My only deviation was in the tomato, which I put as a "bottoming" rather than a topping.
The ordering was: bun, mayo, tomato chutney, pickles, tomato, portobellow mushroom, cheddar cheese, grilled onion, lettuce, bun.
I served this with a raw kale salad and some grilled leeks (not visible in the photo, alas).
In retrospect, this would have been better with the inclusion of mustard and raw onion rather than grilled (I can't believe I'm saying that, but the grilled onion didn't stand up!). I would like to play with the ordering of the pickle and tomato... I think tomato on cheese could be quite nice. I also need to play with my mushroom marinade. I've been going with the basic balsamic, oil, garlic and herb marinade in this recipe, but think some mustard or worcestershire sauce could help, plus a bit more generousity with the salt and pepper.
One last thing, my mayo wasn't really mayo, but a tofu-based "vegannaise" recipe from Mark Bittman's How to Cook Everything Vegetarian book. It's actually very good, though a bit runny, which I blame on the particular silken tofu I used. Next time I will probably make my own mayo, probably one of the best things on earth. Aioli might also be nice.
I lied, this is actually the last thing: the tomato chutney is the bomb. It's a green and red tomato chutney that I made myself from tomatoes in the garden (go me). The recipe is a winner, and I will selflessly not keep it to myself: Tomato and Sultana Chutney.
