Blueberry Custard Bars are helping me get through a sweltering summer in London (between the usual rain days) and having recently finished reading ‘On the Road’ for the first time along with being addicted to Lana Del Rey’s song ‘Ride.’ I am craving getting into my own wheels and setting off for the beach.
After all, that is what summer is for, lazing and making memories with all the extra hours of light. Living in London makes this notion rather difficult, because firstly, I do not have a car and; secondly, I am terrified to get behind a wheel here. The drivers like to stalk crossing pedestrians and watching drivers battle over the tiny piece of asphalt between the white lines would put any lover of driving off the notion here.
Somehow because of this, summer doesn’t feel as fully lived as normally. London streets become cluttered with tourists (more than any other time of year) and all the amazing things to do have to be grabbed early otherwise you miss out. Here a summer vacation involves leaving the country when usually going away is good enough to pack the car and pitch a tent somewhere in little distant New Zealand.
The notion that people don’t think of that as normal to do here is also baffling. How different lives are lived on this globe and how different one person’s ‘normal’ is to another’s. It may seem like I’m complaining, but London comes truly alive in summer, everyone stays indoors in winter and generally it’s because it’s too cold to have outdoor cinemas and no one wants to hang out in the neighborhood locked parks because of the rain.
I just wish we were closer to the beach and summer lasted longer in these Isles.
Blueberry Custard Bars Notes
If you don’t like pistachios or cannot eat them, you can simply sub in a further 46 grams/1/3 cup flour for the shortbread base.
Store bought custard is easiest in this, however, you could most definitely use homemade custard.
The caramel flavor is light in the custard so as to not overpower the blueberry topping or make this too sweet, however, if you love caramel you could most definitely add a further tablespoon, though I recommend trying the recipe as it is first and then amending as per this suggestion.
