Soapberries (Sapindaceae) are a diverse family of temperate to subtropical trees, shrubs and lianas (vines), a few of which have some significance as food - and others as cleansing agents. Photo of lychees on tree by U.S. Department of Agriculture = public domain.

Maple - [Acer]
Maple Syrup grades are established by the USDA. Canada adheres to similar
grading but uses different names. These are not quality grades (there
are no cheap Chinese sugar maples so we presume all the trees are of the
highest quality). These are usage grades, and the makers have little control
as to what grades they'll get in any particular year, that's pretty much up
to the trees.
Native to Southern China and Southeast Asia, these fruits are about 1-1/2" inch diameter. They have a thin leathery shell that's dark yellow and reddish in color (but it turns brown if refrigerated). Very loosely contained within the shell is a translucent white flesh, similar in texture to the inside of a grape, and one bullet shaped seed (which is mildly toxic so don't eat it).
Lychees are commonly sold fresh in Asia, California and other regions with
large Asian enclaves. Canned Lychees are widely available. Some are grown in
Hawaii and Florida.
[longy, long-nan (China); Nephelium longanum]
Native to South and Southeast Asia, this spherical fruit has a thin leathery
brown shell which loosely contains a soft juicy translucent flesh with one
spherical black seed. The flesh is used in Asia in soups, sweets and
sweet-and-sour recipes, but the seed is not eaten. They are available frozen
and occasionally fresh in Asian markets here in Los Angeles. They are also
widely available peeled and canned.
Akee - [Ackee, Achee,
Zakari el Trufi, Y Chocorras el Albatros; Akye fufo (Africa);
Native to tropical West Africa, this pear shaped fruit was transported to the Caribbean on slave ships sometime before 1778, and has been extensively planted there. Weighing between 4 and 7 ounces, the fruit is mostly toxic, including the flesh. Only the white or light yellow arils (fleshy coatings around the seeds) are non-toxic, and only when the fruit is ripe and has opened naturally. If overripe it will again be toxic.
"Salt Cod and Akee" is considered the Jamaican national dish.
Akee is used in other Caribbean cuisines as well. Improperly prepared Akee
is the cause of Jamaican vomiting sickness. The very nutritious arils are
washed and simmered for 30 minutes before use, the water discarded. The
photo shows a fruit at the proper point to be harvested.

[Spanish Lime; Mmmones, Quenepa, Genip, Chenet, Canepa, Skinip,
Kinnip; Anancillo (Cuba); Ackee (St Vincent, Grenadines, Barbados); Melicoccus bijugatus]
Native to northern South America, this fruit was introduced into Central
America, Mexico and the Caribbean in pre-Columbian times, and into Africa,
India and tropical Asia since then. It has a hard but thin green outer
skin surrounding a tart yellow pulp. It is generally eaten fresh by
cracking the shell and sucking the pulp off the single large seed. This
is not real easy, as the pulp is thin and adheres well to the seed. The
taste is lightly sweet-sour with an apricot like flavor. There are
varieties which are more sour, and eaten in southern Mexico with chili,
salt and lime. The seeds can be roasted and eaten. The photo specimens
were about 7/8 inch diameter, 1 inch long and weighed 0.25 ounce each.
They were bought from a large Hispanic market in Los Angeles (Burbank)
for 2016 US $2.99 / pound.
This red, pink or yellow fruit, about the size of a small chicken egg, is significant in Southeast Asia but production is ramping up in other tropical areas including Hawaii. Starting in 2008 fresh fruit have been allowed into the U.S. while previous they had to be frozen.
Rambutan's single seed is surrounded by a firm but juicy sweet pulp,
much like a Lychee and of similar flavor and texture. They are also
frozen, made into preserves and canned for shipment to non-tropical
regions. The photo specimens were up to 2-1/4 long by 1-3/4 diameter
weighing 1.4 ounces. A 1.25 ounce Rambutan will yield about 0.63 ounce
of edible flesh (50%). Yield is about 40% from frozen. The seeds are
bitter and slightly toxic so should be discarded. A recent purchase
at a very large Asian market in Los Angeles (San Gabriel) was at
2016 US $1.59 per pound, much lower than a couple years ago.
[Cotopalo (Spanish); Olho de boi, Pitomba-rana, Pitomba de Macaco
(Portuguese); Pitoulier Comestible (French); Talisia esculenta]
Native to the Amazon Basin, this medium size tree produces spherical fruits
between 5/8 and 1-5/8 inches diameter. The thin brown skin covers a golden
yellow pulp with an apricot-like texture. It is juicy, aromatic, slightly
tart and faintly resinous - described as a combination of apricot and lemon.
It is eaten fresh, and used to make juice. Seeds are roasted to treat
diarrhea and sap from the tree is used to poison fish. This pitomba should
not be confused with a myrtle fruit also called

Native to the Amazon Basin, this climbing plant produces fruits about the size of coffee beans, but with twice as much caffeine. As you might expect, it is used mainly as a stimulant in beverages, and has been for hundreds of years. South America gets most of its caffeine from guarana, not coffee.
Uses include carbonated soft drinks, energy shots, teas, and capsules.
It is also being studied as a weight loss agent, with positive results.
For this use it is mixed with other substances suspected of aiding weight

[Soapnut; Doda, Kanma, Thali (India); Sapindus mukorossi]
These nuts, long used in India and ingrained in the Ayurvedic lifestyle, are gaining attention from North Americans seeking to reduce the number of chemicals and artificial ingredients in their lives. They are used both for laundering clothes and as a shampoo. Because this shampoo is a mild insecticide it has been used for removing head lice.
Broken shells (discarding the hard seed) are tossed in with the
laundry, or powdered forms are used. The photo specimens, purchased from
an Indian market in Los Angeles, were about 7/8 inches diameter.
Horse Chestnut -
[Conkers, Aesculus hippocastanum]
Native to the Balkan region of Europe, horse chestnuts are somewhat toxic, to people and horses. Their main culinary use is is Bavaria, where they were planted in beer gardens for their very dense shade to keep ice from melting. Today they provide shade for the customers.
During both world wars they were used to produce acetone, which was in
turn used to produce cordite explosives. They have also been used to make
soap for washing linen (they are "soapberries", after all).
