Peel and slice peaches into small chunks
Combine peaches, ⅓ cup of sugar and lemon juice in a bowl
Cover the bowl and allow peaches to macerate in the refrigerator for at least 1 hour
Strain peach sauce into a separate bowl. Pure 2/3 of leftover peach mash in a food processor and add to peach sauce. Set other 1/3 peach mash aside in a bowl.
In a medium sauce pot, combine cream, milk, ⅔ cup of sugar, salt and vanilla paste from your vanilla pod.
Simmer cream mixture over medium heat until small bubbles form on the side. Do NOT let it boil!
Remove from the heat
Whisk together egg yolks with ⅓ cup of sugar in a medium bowl until sugar dissolves and eggs are a light yellow color.
Slowly whisk in one cup of the hot cream mixture to temper the eggs.
Pour the egg mixture back into the cream mixture in the pot to create a custard
Simmer on medium low for about 8 minutes, stirring constantly until custard coats the back of the wooden spoon (about 170 degrees)
Pour custard into a fine mesh sieve over a heat proof bowl that is placed in a larger bowl filled with ice.
Cool down the custard, stirring a few times.
Stir in peach sauce until combined (save peach mash for end)
Cover bowl with plastic or transfer to container with a lid
Pop in refrigerator to chill for at least 2 hours or overnight
Pour peach ice cream into your ice cream maker.
Churn for 25 minutes until it looks like soft serve ice cream (or according to manufacturer instructions for homemade ice cream)
During the last 30 seconds, add in your peach mash until just combined.
