In a large bowl, whisk together eggs and sugar till smooth.: As you begin, you will notice the sugar dissolving into the eggs , creating a glossy, pale yellow ribbon when lifted with the whisk, and a faint sweet aroma will start to rise. This step matters because it helps the sugar integrate fully, preventing gritty pockets in the finished texture. If the mixture feels gritty after a minute of whisking, keep working until it becomes satin smooth. A common mistake is rushing this stage and leaving un-dissolved sugar , which leads to an uneven mouthfeel in the ice cream. Take your time, use a steady wrist, and check the bottom of the bowl to ensure all granules have dissolved.
Place diced peaches in a medium bowl and mash a few times with a potato masher.: When you press into the diced peaches , their juices will smell intensely fruity and bright, and the flesh will yield easily under the masher, offering a mix of puree and small chunks that provide textural interest. The reason for mashing only some pieces is to balance smoothness with bite, giving the ice cream both wholly infused peach flavor and delightful pockets of fruit. Avoid pulverizing everything into a puree because you will lose the contrasting texture that makes each spoonful interesting. If your peaches are especially juicy, watch for excess liquid, and reserve a little of the mash if you want more prominent fruit pieces later.
Stir the peaches into the eggs, then mix in cream, half and half, vanilla and salt.: At this point, the scent becomes complex, with the warm dairy notes of heavy cream and half and half blending with the bright peach perfume. You will see the mixture take on a pale peach hue and a velvety consistency as the liquids marry. This technique matters because gently folding preserves air and keeps the texture light while ensuring even distribution of fruit. Stir until homogenous but do not overmix, which can break down fruit pieces and create too much foam. One mistake to avoid is adding cold dairy straight from the fridge when components are not compatible in temperature, which can cause slight curdling; temper by stirring slowly and ensuring the ingredients combine smoothly.
Pour the mixture into the freezer container of ice cream maker and process according to manufacturer's instructions.: As the churn begins, listen for a steady, rhythmic hum and pay attention to the texture changing from liquid to soft set, becoming thicker and lighter as air incorporates and the temperature drops. The aroma will intensify, and you might notice steam like breath in the cooler air around the machine. Processing is essential for creating small ice crystals and a creamy, scoopable structure. Follow your specific machine's timing, since overchurning can make it too firm while underchurning yields a loose, icy result. A typical problem is failing to pre chill the freezer bowl if required, which leads to poor freezing and a grainy final product, so check your machine's prep needs beforehand.
