Chili Oil Smashed Cucumbers

In a small pot, heat oil until starting to smoke, then remove from heat.  Meanwhile, in a medium heatproof bowl or jar, whisk to combine all other ingredients. Slowly pour hot oil over the spices, letting it sizzle through evenly, streaming gradually and carefully to control the overflow. Whisk to incorporate fully and let cool completely. Cut each cucumber into three pieces, then use the flat size of your knife to smash each piece into two craggy halves. In a large bowl, toss smashed cucumbers with chili oil, sesame oil, and MSG until evenly combined, then season with salt to taste.
