Soften the Onion and Soak the Breadcrumbs
10 Minutes
Low heat, about 120°C (250°F)
Melt the 20 g butter in a small pan and cook the finely chopped onion over low heat for about 5 minutes until soft and transparent, not browned. Set aside to cool. Warm the whole milk until lukewarm and soak the breadcrumbs in it for 5 minutes until soft.
Browning the onion would darken the sausage — keep the heat low and stop as soon as it turns transparent.
Done when: The onion is soft and glassy, and the breadcrumbs have swollen into a soft paste.

Grind and Mix the Sausage Meat
15 Minutes Active, 30 Minutes Chilling
Chill, 4°C (39°F)
Grind the chilled pork shoulder and chicken breast through the fine plate of a mincer into a cold bowl. Add the soaked breadcrumbs, cooled onion, heavy cream, beaten eggs, salt, white pepper and nutmeg, and mix with cold hands or a spatula until the paste is smooth, sticky and uniform. Cover and chill for 30 minutes.
Mix just until uniform — over-mixing makes the sausage rubbery. If the paste feels warm, chill it again before stuffing.
Done when: The paste is smooth, pale and sticky, and holds together when you lift a spoonful.

Stuff the Casings and Twist the Links
15 Minutes
Room temperature, about 21°C (70°F)
Rinse the soaked pork casings and slide one onto the stuffing tube. Fill steadily, easing the casing off the tube as it fills, and twist into 8 links of about 15 cm (6 in) each. Prick any air bubbles with a clean pin.
Fill loosely, not tight — the sausages swell as they poach, and overfilled casings burst. Tie the ends well.
Done when: Each link is plump and even, with no air pockets and no paste leaking from the ends.

Poach Gently Until Cooked Through
30 Minutes
Poaching water, 80°C (176°F); sausage must reach 71°C (160°F)
Heat a large pot of water to 80°C (176°F) — steaming, never boiling. Lower the sausages in and poach for 30 minutes, keeping the water below a simmer, until the centre of the thickest sausage reaches 71°C (160°F). Lift out and cool briefly.
Boiling water bursts the casings in seconds — if you see bubbles rising, turn the heat down at once.
Done when: The sausages are firm to the touch and pale white, and the centre of the thickest one reaches 71°C (160°F) on a meat thermometer.

Fry the Apples and Brown the Sausages
12 Minutes
Medium heat, about 175°C (350°F)
While the sausages poach, melt the 20 g butter in a wide pan and fry the apple slices with the sugar over medium heat for about 8 minutes, turning once, until golden and tender. Set aside and keep warm. Melt the 15 g butter in the same pan and fry the poached sausages for about 8 minutes, turning often, until the skins are golden brown all over.
Fry the sausages gently — a fierce heat splits the skins. Roll them often so they brown evenly.
Done when: The apples are golden and tender, and the sausages are evenly browned with a crisp skin.

Serve the Boudin Blanc
2 Minutes
Serving temperature, about 60°C (140°F)
Lay two sausages on each warm plate with a spoonful of caramelised apples, and serve at once with mashed potatoes or a green salad on the side.
Serve the sausages hot from the pan — they cool fast, and cold boudin blanc turns heavy and greasy.
Done when: The plate shows golden sausages with glossy apples, and the sausage is pale and steaming when cut.

Lift the fried sausages onto warm plates with the caramelised apples, and serve at once with mashed potatoes or a green salad. Cut into a sausage at the table — the inside should be pale, smooth and steaming, never pink or grey.
