Steps to make this recipe

Step 1: Prep your cukes

Slice your cucumbers in rounds. I wanted mine to be a little thicker, but you can cut them to your desired thickness. Set aside. 

Recipe Tip

At this point, to add some extra flavor to your cucumbers, you can salt them to let out their excess moisture, wash and dry. 

Step 2: Make your wasabi mayo
Make your wasabi mayo. In a small bowl, mix together mayo, wasabi, rice wine vinegar, salt and sugar until all combined. Set aside.

Step 3: Sear your sushi-grade tuna
​Next, take your ahi tuna and add in a plate with sesame oil and then coat it in a plate of ​your assorted ​sesame seeds.  Sear in a skillet, pan or on a grill 20-30 seconds on each side until the outsides of the ahi are a lighter brown color, while keeping the ahi medium rare inside. Remove from the skillet, cool and slice​ to your desired thickness for the bites.​

Step 4: Assemble!
Assemble! Take your cucumbers, add on your sliced seared ahi tuna, top with a dollop of wasabi mayo, and finish with chives and edible flowers. Serve!​

Tips, Tricks and Substitutions

Where can I find wasabi paste? You can use fresh wasabi (as one option) or paste. Additionally, most local Asian stores should have all kinds of wasabi. If you can find, I highly recommend grating fresh wasabi!

What else can I use this wasabi mayonnaise on? You can use it on anything! Some ideas are roasted asparagus dipped in the mayo, on roasted bell peppers as a side, or even as a dressing for a tomato salad. the ideas are endless!

Can I use something other than ahi tuna for this recipe? Seared salmon, yellowtail or albacore would be great for this! You can also do raw scallops too as another idea!
