Xá Xíu Chay | Vegan Char Siu (BBQ)
Xá Xíu = Char Siu
Chay = Vegetarian
Xá Xíu originates from 叉燒, which is Cantonese for fork cooked. It originates from a long fork roasted over a spit fire. Basically, it’s barbecue.
Guilt Free Barbecue
Xa xiu chay is a guilt free version of its traditional meat counterpart. This flavor packed, beautiful deep red barbecue is made without powder packets and food dye.
If you’ve never had Char Siu it’s important to note that this barbecue is traditionally made to be sweet and savory. At no point is char siu ever just salty. The recipe is known for the sticky glaze that’s sweet, peppery, and slightly salty.
King Trumpet Mushrooms is our hearty, vegan friendly “meat.” It’s a traditional recipe that will have you drooling long before it’s plated.
The best part, IMO, is it will introduce you to ingredients that you might not have worked with before. It provides a little foundation for how to play with these ingredients in the future.
MEET THE PLAYERS
Nấm Đùi Gà | King Trumpet Mushrooms
King Trumpet Mushrooms are an amazing meat substitute. They’re hearty, meaty, and when pulled apart look like shredded chicken.
They are subtle, and delicate in flavor, which makes them perfect for absorbing all the seasonings of this marinade. These mushrooms from top to bottom are a vegan eater’s dream.
Red Yeast Rice
Red yeast rice is our special ingredient. You really can’t beat the fact that it’s red, fermented and an all natural food dye. It boasts so many incredible health benefits, but in culinary applications it’s been used since 1600 B.C.
When prepping the red yeast rice, place it in a mortar and pestle and crush until it’s a fine red/pinkish powder. Alternatively you can place all the marinade ingredients into a blender and process until smooth.
Maltose
Meet the tackiest sugar that is nowhere near as sweet as any regular sugar or syrup. Maltose is 30-40% less sweeter than your normal sugars. If you flip this ingredient upside down it won’t move. This is how thick it is.
Maltose is thicker than molasses. The easiest way to work with maltose is with a scale. Oil a spoon, scoop out a bit and weigh it.
An alternative to a scale, oil your measuring spoon and knife. If it’s still too difficult to work with, heat the cup for 15-20 seconds in the microwave and try again. Note that maltose holds heat really well so be careful not to burn yourself.
SPECIAL TIPS
Cleaning the King Trumpet Mushroom
If you don’t have ready to eat, triple washed mushrooms, it’s really important to remove dirt, bacteria and potential bugs. There’s nothing worse than eating unintentional crunchy granular bits in an otherwise smooth textured mushroom.
An easy cleaning tip, sprinkle your mushroom with flour or cornstarch, salt and plunge it into water. Gently mix it around. Use your fingers to feel around the gills and remove the grit. Rinse and place on a towel right before using.
Clean the mushrooms only when you’re ready to use. Water is not your mushroom’s friend when it comes to storage and advance prepping.
Braising
Char Siu might traditionally be on a spit fire fork over an open flame, but there are plenty of meat based recipes done in a pan. It’s more convenient and important for the mushrooms to develop flavor.
The heartiness of King Trumpet Mushrooms allow them to do really well with braising. We start off with a decent amount of liquid. Piercing the mushroom lengthwise with the tip of your knife around the base helps to absorb more spices.
We start the first part of braising with the lid on, in order to really penetrate the flavor into the mushroom.
It’s important to remove the lid for the last 15 minutes to allow the braising liquids to cook down and get more concentrated. This helps us to remove any excess water that might have diluted our initial braising liquid.
HOW YOU SHOULD EAT THIS
Vegan Char Siu can be eaten with your favorite fried rice, noodle soups, gua baos, over plain rice or in a banh mi. It can definitely stand on its own, sliced and/or diced in a steamed bao too!
FINAL THOUGHTS AND NOTES:
King Trumpet Mushrooms increase in umami around 140 to 158 degrees F.
Use a blender if you don’t want to crush your red yeast rice by hand with a mortar and pestle. Don’t forget to reduce your braising liquids for an incredible char siu sauce packed with flavor.
Vegan/Gluten Free Tips
If you’re cooking for a vegan and can’t find maltose, don’t substitute for honey. It’s not vegan. I haven’t experimented with maple or corn syrup, but those would be suitable substitutes.
You would need to decrease the amount. It’s not 1:1 because these sugars are much sweeter. Start with at least 30% less and go from there.
If you’re stateside make sure it’s organic sugar. Apparently in the US, we’re the only country who still uses bone char to process sugar which makes regular sugar not vegan friendly.
If you happen to be gluten free, make sure to use tamari or find a gluten free soy sauce that would work.
Amino acids tend to be really salty so just beware to adjust accordingly. Check your hoisin sauce before using or purchasing, because those are typically not gluten free. I usually have to buy these labeled, “gluten free.”
