I find it really odd that salmon and eggs on toast, or avocado toast count as "dry lunch". Even his ham sandwich has a slather of butter and tomatoes. Just how wet are Chinese lunches? Is everything less liquid than a soup counted as dry?
Actually sort of. I mean I guess what you would call a soup. Though the Chinese would just consider that a sauce. The put that shit on everything. Well different sauces. Here's a random picture of a Chinese school lunch.
You see how the veggies are glistening? They're covered in a sauce made with cornstarch and broth. Even the fish has a layer of sauce on it.
So yeah, a sandwich would be pretty dry. But that's not really what they're talking about.
In Chinese food, there's an insane amount of seasonings that basically go in everything. At a minimum they use something called 5 spice which is a mixture of you guessed it, 5 spices. So the dry they're referring to is actually seasoning. So something like a subway sandwich with italian dressing, salt, pepper and oregano wouldn't be dry in the way they're using it. They're really just referring to the sandwich being unseasoned. Also, here's a tip, if you're going to make a sandwich, season it. Even just adding salt and pepper will make it taste way better.
I've been making an SPG blend for a while on and off based on proportions my buddy used for his brisket rub. Sometime last year he started keeping a whole jar of it on hand and seasoning everything savory with it rather than just using salt when it's called for. The biggest difference between his and mine is that he uses sea salt and I use regular table salt. The flavor is slightly different and I don't get the big crystals, but it's still pretty great.
He turned me into a believer. I've started keeping my own jar and that's my base spice for everything. Chicken, fish, beef, pork, veggies, whatever. Most things get extra like paprika, chili powder, oregano, parsley, or whatever the meat calls for, but everything gets at least those three. Even my homemade mayo gets it, which means it goes on all my sandwiches as well.
