Embodiment 1

[0024] Step 1: Take eggs of uniform size, separate the egg white from the egg yolk, put the egg yolk into a round mold, add 1mL of purified water to each egg yolk, cover with plastic wrap, and freeze;

[0025] Step 2: Peel the sweet potatoes and purple potatoes respectively, slice them, steam them in a pan, crush them into mud, heat and stir-fry the purple potatoes until the water content is 20%, and cool to room temperature. During the cultivation process, the cake skin will be heated, leaked, and collapsed. If the moisture content is too high, it is easy to breed mold. Therefore, considering the number of microorganisms and product quality requirements, the moisture content of purple sweet potatoes should be controlled at 20%;

[0026] Step 3: Add 40g of sweet potatoes to 200g of high-gluten flour, then mix 60g of butter, 0.8g of glyceryl monocaprylate and 60mL of hot water, stir until completely dissolved, slowly add to the high-gluten flour, and stir while pouring until Fl...

Embodiment 2

[0034] Step 1: Take eggs of uniform size, separate the egg white from the egg yolk, put the egg yolk into a round mold, add 1mL of purified water to each egg yolk, cover with plastic wrap, and freeze;

[0035] Step 2: Peel the sweet potatoes and purple potatoes respectively, slice them, steam them in a pan, crush them into mud, heat and stir-fry the purple potatoes until the water content is 21%, and cool to room temperature. During the cultivation process, the cake skin will be heated, leaked, and collapsed. If the moisture content is too high, it is easy to breed mold. Therefore, considering the number of microorganisms and product quality requirements, the moisture content of purple sweet potatoes is controlled at 21%;

[0036] Step 3: Add 50g of sweet potatoes to 250g of high-gluten flour, then mix 80g of butter, 1g of glyceryl monocaprylate and 80mL of hot water, stir until completely dissolved, slowly add to the high-gluten flour, and stir while pouring until the flour A...

Embodiment 3

[0044] Step 1: Take eggs of uniform size, separate the egg white from the egg yolk, put the egg yolk into a round mold, add 1mL of purified water to each egg yolk, cover with plastic wrap, and freeze;

[0045] Step 2: Peel the sweet potatoes and purple potatoes respectively, slice them, steam them in a pan, crush them into puree, heat and stir-fry the purple potatoes until the water content is 22%, and cool to room temperature. During the cultivation process, problems such as heating, leaking, and collapse of the cake skin will be caused. If the moisture content is too high, it is easy to breed mold. Therefore, considering the number of microorganisms and product quality requirements, the moisture content of purple sweet potato is controlled at 22%;

[0046] Step 3: Add 60g of sweet potatoes to 300g of high-gluten flour, then mix 100g of butter, 1.2g of glyceryl monocaprylate and 100mL of hot water, stir until completely dissolved, slowly add to the high-gluten flour, and stir wh...

Abstract

The invention relates to purple sweet potato egg-yolk puff. The components of the purple sweet potato egg-yolk puff comprise high-gluten flour, mashed sweet potatoes, hot water, butter, low-gluten flour, lard, mashed purple sweet potatoes, frozen egg yolk, glycerol monocaprylate, yolk liquid and semen sesami nigrum. The purple sweet potato egg-yolk puff has the advantages that ordinary egg yolk isused for replacing salted egg yolk, purple sweet potatoes and sweet potatoes are added in stuffing and flour skin, and the taste of the egg-yolk puff is integrally improved to be slightly sweet fromsalty, which expands the range of eating people; in view of the nutrition of the purple sweet potatoes, sweet potatoes and egg yolk, the nutritive value of the egg-yolk puff is increased; the glycerolmonocaprylate is added as a preservative, especially a novel non-toxic efficient broad-spectrum preservative, gram bacteria, moulds and yeasts all have inhibitory effects, and the glycerol monocaprylate also belongs to a lipophilic non-ionic emulsifier, has dual functions of corrosion prevention and emulsification, and is a substance with very high safety.
