I got it from your video on YouTube for contoured cookies. I used the ratio of 1 egg yolk to 1 tsp milk and put in a low oven. However because my sister is lactose intolerant I have used soya milk. I wonder if that is what has made the difference!
Can't say, as I haven't rigorously tested this glaze (a compilation of standard washes) even with regular milk. I tried it once for that video, and experienced some cracking that I never resolved (as I noted in the video), so I can't offer much more assistance here. I just didn't find it greasy.
