Tartelette au Feijoa et Chocolat Noir – Feijoa & Dark Chocolate Tartlets

DSC_3897 s
Making these tartlets was a last minute decision, wait, make that an impulse! The initial intention was really to make some of Sugino’s fig tartlets since we finally managed to get some good figs in Singapore this season. Last year’s were horrid. But then came along feijoas, which were on sale at our local supermarkets. I’d seen them last year but they were very expensive, since only one (premium) supermarket carried it, the price was kinda monopolised. That is what happens over here unfortunately yes… But this year, the prices dropped by more than half! No more excuse for not trying them. They were packaged as “zeijoas” since this batch were not from their native South America but New Zealand, where they are widely cultivated and grown by the kiwis in their backyards as a fruit tree. No prizes for how the name “zeijoa” came about but I’m hoping that our folks over here would not take this name too seriously as the actual one!  More curiously, these “zeijoas” were marketed as “Causasian guavas”. I wonder how many actually knew that the common guava we’d been eating originated from Central and South America as well. Despite the slight similarities in taste , I wonder why would anyone do that. Oh well, I guess the logic is functional, mapping the known against the unknown, the familiar against the unfamiliar. But sounds kinda silly if you ask me, likening one to brand fettuccine as the “Italian mee kia” and yes in case you are wondering, it is being done by one of the popular brands for electrical goods, on their latest noodle making machine! Anyway, we’d digressed.

My first tasting of the feijoa I bought and I was blown away. The fruit had just beautifully ripened, with the core of the insides really gelatinous and sweet. The fruit was also highly perfumed, a bouquet of aromas which reminded me of bubble gum candy and a “grape-flavoured” soft drink called “Qoo”. It can be easily eaten by slicing lengthwise into two and scoop out the flesh as how one would eat a kiwi, with just a dessert spoon As we work towards the skin, the texture changes and becomes more… yes, you’d guessed it, guava-like, slightly fibrous and grainy in texture while the taste also developed from being sweet to sour. It is more juicy than the average guava. The progression of flavours was really interesting and I thought won’t it be great if I could put this into pastry?! And indeed I did! So here’s my little impulsive weekend baking venture, Tartelette au Feijoa et Chocolat Noir – Feijoa and Dark Chocolate Tartlets.

As with most pastries I try to make, the first thing to do is the conceptualisation. I kept the composition simple and the tartlets comprise of 5 components, i.e. a standard pate sucree as the base, praline feuilletine au speculoos at the bottom for the crispy and nutty textures, and then a layer of gelee au feijoa, followed by a ganache au chocolat noir and finally a glacage au chocolat.

The feijoas used have to be ripened for the tarts to work beautifully. Unripe feijoas has a more fibrous core as seen in the photo above, void of the gelatinous innards as in the earlier photo. Ripen feijoas should yield so every slightly when one attempts to press on the exterior. Unipe ones would just be hard like guavas. But should one slice through a feijoa to realise that it is one or two days too early to have done so, all is not lost. The flavours of the fruit can be accentuated through maceration, which simply requires some granulated sugar to be added to the scooped out pulp and left covered for a few hours in the fridge. I left mine chilled overnight and next morning, the flavours mellowed wonderfully.

For the tartlets, I’d used two types of tart rings, the larger ones for the sweetcrust pastry base while the smaller ones were used to set the gelee and ganache. Alternatively, the gelee and ganache layers can also be cut out with pastry or cookie cutters once they have set. So it is not an issue if one doesn’t have these different types of tart rings.
DSC_3855 s
The macerated feijoa pulp is then pulverisedand heated it to 65 degrees Celsius before reconstituted gelatine was added. Since this is a really new fruit to me to experiment with, I’m not entirely what effects the enzymes in the fresh fruit would have on the proteins in gelatine, as how those in fresh kiwi would break them down. So I’m not taking chances on that. The heated concoction is pour into the tartlet rings which double up as moulds here as I’m trying to minimise attrition. These feijoa jelly discs were left in the fridge to set overnight, together with the sweet crust almond pastry dough.
DSC_3865 s
The praline feuilletine layer is easily made with just four components, i.e. chopped hazelnuts, gavotte biscuits, melted milk chocolate and praline paste. Traditionally, praline paste is made from ground hazelnuts but I’d decided to use speculoos instead!
DSC_3878 s
The milk chocolate can be melted in a microwave or over a bain marie. Otherwise you can do what I did, i.e. to leave the the chopped milk chocolate chunks in a metal bowl placed on top of my heated oven while the tart bases are baking inside! After the milk chocolate has nicely melted, it is mixed with crushed gavotte biscuits followed by chopped roasted hazelnuts and the speculoos paste.
DSC_3872 s
The tartlet rings were dislodged from the feijoa jelly and used to set the prepared dark chocolate ganache. Those familiar with pastry making would know that ganache can be made easily by pouring hot cream over a bowl of chopped chocolate. Some time is given for the chocolate to melt before mixing well. A little butter and salt is added at the end to give the ganache a luscious taste and beautiful shimmer.
DSC_3883 ss
After the chocolate glaze is prepared, the tartlets are now ready for assembly. I’d planned to brush the interior of the tartlet shells with a layer of chocolate to prevent the moisture from the feijoa jelly from coming into direct contact with the pastry crust but later found it be unnecessary. But one can always do with some caution here. so it is entirely up to the individual to take the risk or not.
DSC_3889 s
A thin layer of praline feuilletine au speculoos is first pressed into the base of the tartlets with the back of a dessert spoon or offset spatula.
DSC_3895 s
The set ganache layers are then stacked together with the feijoa jelly before being robed with the chocolate glaze. These are then placed carefully over the praline feuilletine layer and finally the tartlets are garnished with roasted hazelnuts and gold leaf.

Several things came to my mind when I first had everything together. Firstly, the layers are far too thick than what they really ought to be. That is when the greediness in me sets in. Will probably try to work thinner layers next time, Secondly the temperature of the glaze was too low before being poured over the ganache and jelly layers. This resulted in uneven robing of the ganache as the gelatine component in the glaze set and thickened too quickly in some areas. These are things which I need to keep in mind and work on for future. On a positive note, the tartlets taste really good! I’m surprised that the pairing between feijoa and dark chocolate worked out so well. Maybe it would be good to explore other possibilities on working with feijoa next time!

      thanks Edith! lots of room for improvement though… especially the glaze!

  2. The composition doesn’t look simple to me at all, this looks delicious as always.

    Morning Alan: These looks so delicious.

    They look quite easy to make, once the prep is done. Just can’t look at it as a whole but as

    separate steps, and it isn’t so daunting.

    I’m wondering what could be substituted for the freijoas, if I can’t get them here.

    What size rings or biscuit cutters did you use?

    Have a Joyful Day :~D

  4. These tarts look so perfect! I’m currently stuck 1) finding a good tart recipe, and 2) baking a set of perfect tart shells. I’d love to give your tart recipe a try. Do you have any tips for lining tart rings and baking tart shells?

  6. Now that I’m situated in Australia, I’ve been seeing tons of feijoas in the market recently but didn’t know what to do with them! the gelee sounds like a fantastic idea!

      You know what? I was just visiting your big earlier today checking out the baking supplies outlet in HK. Didn’t realise you’d relocated to Sydney and finished your LCB course! Congrats!
