   Place eight 4-ounce ramekins in a large roasting pan.
4. 4
   Bring a large kettle or pot of water to a boil.
5. 5
   Make caramel In a saucepan over medium-high heat, stir together sugar, water, and lemon juice (if using), stirring to combine.
6. 6
   Do not stir again.
7. 7
   Cook, washing down sides of pan with a pastry brush dipped in water to prevent crystals from forming, until caramel is amber, about 8 minutes, swirling pan to color evenly.
8. 8
   Remove from heat, and immerse bottom of pan in ice-water bath for 3 seconds to stop cooking.
9. 9
   Dry bottom of pan.
10. 10

11. 11
    Make custard In a small saucepan, heat milk with half the sugar (1/4 cup plus 2 tablespoons) over medium heat just until mixture starts to steam and bubble around the edges, 5 to 6 minutes (do not let it boil).
12. 12
    Meanwhile, whisk egg yolks In a large mixing bowl, whisk together the eggs, yolks, remaining sugar (1/4 cup plus 2 tablespoons), and salt.
13. 13
    Temper eggs Add a ladle of hot milk mixture to the egg mixture and whisk to combine.
14. 14
    (This is called tempering and it prevents the eggs from curdling.)

16. 16
    Gradually whisk in remaining milk mixture.

23. 23
    Chill and serve Remove pan from oven.
24. 24
    Use tongs to carefully remove ramekins from hot-water bath and place on a wire rack for 30 minutes.

    Then cover with plastic wrap and chill for at least 8 hours (or up to 3 days).
26. 26
    To unmold, run a sharp knife around inside of ramekins, and place a rimmed serving plate upside down over the top of each.
