Beetroot powder
This is the product I used to colour the bread. P.S. you can adjust the amount for a stronger or softer colour... but remember it is not flavourless: you can taste the beetroot! Open link ↗ (affiliate link)
Antipastini · Soft coral-pink buns for shrimp rolls
Super soft pink Shokupan buns made with tangzhong and beetroot powder, perfect for toasting in butter and filling with shrimp.

Mix 20 g of bread flour with 100 g of whole milk. Cook over low heat, stirring constantly, until it turns into a thick cream, ideally reaching about 65 °C. Cover and let it cool slightly.
Mix the 150 g of lukewarm whole milk with the sugar, honey and dry yeast. Leave it for 10 minutes. Dissolve the beetroot powder in some of this milk so no lumps form.
Add the egg, the slightly cooled tangzhong, the bread flour and the milk powder. Knead for about 5 minutes, then work in the salt.
Gradually add the soft butter and keep kneading for another 10–12 minutes, until the dough is elastic and very soft. Do not correct the texture by adding more flour. Finish with 5 final slaps on the counter.
Cover the dough and let it rise for about 50–70 minutes, until visibly bigger.
Divide the dough into 8 portions of about 102 g. Round each one, cover them and let them rest for 15 minutes.
Roll each portion into a small rectangle. Fold the two long sides into the centre, close the dough and pinch the seam well. Roll gently into a log about 12–13 cm long.
Place the buns seam side down in a buttered tin of about 30 × 20 cm. Make two groups of four and leave very little space between the buns.
Cover and let the buns rise for another 45–60 minutes. They should become puffy and almost touch each other.
Gently brush the tops with a little milk, without using egg. Bake in a conventional oven preheated to 175 °C for 18–22 minutes. The ideal internal temperature is 92–94 °C.
As soon as they come out of the oven, brush the buns with a little melted butter and cover them with a tea towel for 15 minutes. This keeps the crust especially soft.
Once the buns are cool, slit them from the top without cutting all the way through. Briefly toast the sides in butter, then add the shrimp filling.

Tangzhong (also known in the West as water roux) is an Asian bread-making technique where a small part of the flour and liquid (water or milk) is cooked first in a 1:5 ratio up to 65 °C. This gelatinises the starches, so the dough holds more moisture and turns out incredibly soft and keeps longer.
Sofi’s tips
01Do not add more flour even if the dough seems very soft: as you keep kneading it becomes elastic.
02Use 8 g of beetroot for pastel pink, 10 g for coral pink, and do not go above 12 g.
03Avoid brushing the buns with egg and do not go above 175 °C, to keep the colour better.
04The internal temperature of the baked buns should be between 92 and 94 °C.
05Brush the hot buns with melted butter and cover them for 15 minutes for a very soft crust.
